Need help choosing a dual sim phone

Hello everyone,
I looked around all of the internal forums and general appeared to be the best.
In short I am looking for a good dual sim phone that doesn't need a soft reboot to switch between sims. I have to be able to get calls on both, essentially looking like call waiting is working.
Here are must haves:
Unlimited ring tone assignment (the dual I have now limits me to 10 ringtones). I have a ton of referral sources calling as well as personal calls and I need to know who I can ignore by sound and who I have to answer.
External memory SD or Micro (for the ringtones) unless it has a large enough internal
Dual sim of course...
AT&T service currently, and would prefer to stay but not married to them. Lesser of 5 evils basically (1900MHZ)
My preferences:
I've had my fun playing with all of the stuff from here for windows mobile, but I just can't take the slow speed anymore. I am open to a smartphone or non smartphone, but if it is a smartphone I need it to react nearly instantly.
I would prefer a flip phone, mainly because I'm getting frustrated with applying new screen covers to protect my screen so often. So I guess I should say, if it's a touch screen non flip then I'd like to be able to buy 50 precut screen covers out the gate (not really concerned about price). (currently have a Fuze and I'm sick of the snail speed and still can't find the precut screen covers - although I have determined how to increase speed, and will do so once I get my new phone... drive 80 MPH and throw it out the window!)
I really think that about covers it. When I do a Google search for a dual sim I just end up at one of a hundred Chinese wholesale sites, and most of their phones have their own OS with tons of limitations.
Thanks ahead of time! (btw price isn't a big issue, although less cost is always better)
So in browsing through old posts here I found Expansys and in looking at them I found this...Samsung B5702 ... it may very well be what I want. The price seems pretty over the top for a non smart phone, but I'm guessing it's cheaper elsewhere... Does anyone happen to have this phone who could give me their take on it? Thank you,

So I bought the LG Ks660 from Amazon... could have paid about $30 less through another lesser known, but I figured it's worth the $30 to know I'd get it and it would be easy to return if it blows.
I paid $260 for it, which is about $160 more than your typical dual sim/dual standby Chinese cells but I hope it has what I need. The one dual I have from China limits the ringtones, which to me is a must these days on phones.
I'll post the results of my first few days of testing in case anyone else has two cell lines but is sick of carrying the two phones. Due to arrive tomorrow... I had to choose impatient shipping...

Dual SIM adapters

Hi,
I'm looking for a dual sim adapter for my Nexus One.
Basically I want to use the second sim to make calls at the times I got expensive rates with my main card.
I'd prefer a non cutting model. Also, as far I read, the analog ones consume less battery.
Prices go from $5 to €60 which seems like too big a difference.
Do you know which ones, if any, work fine with the Nexus One?

I don't think the Nexus has the software support for switching sims.

I was not talking necessarily about internal android software support, but even then, there is at least this:
forum.xda-developers.com/showthread.php?t=635473
or
www xda-developers.com/android/multisim-utility-available/
There it's where I read about analog adapters being used with android.
PS: sorry for not posting 100% usable links, being new on he forums I was not allowed

GPS/PCI Express Break-off from Hardware Breakdown Thread

I wanted to break this off since the other topic was looking to be mostly about the LCD's

I wanted to see if the blank sockets on the system board were active. So I grabbed my multimeter and tested each pin to see if any delivered power. I don't know if these sockets are controlled by software, but it looks like these sockets are inactive.

I'm an electronics tech (avionics really) just so you know my background, and I am by no way a programmer i just hack my way throught when i need... poorly at that. I'm a long time reader but don't post much.
I havent taken mine apart yet, I bought it for the wife to use as an ereader she was using her evo before and already has bad eyesight I just dont think reading on that small screen is good for her. However we planned on returning it today because she couldn't get anything to work... But i loaded VAGAn-Tab rom on it and she likes it ALOT more now, but we still might be returning it (she thinks it to big and heavy to hold). So all I have to work with is the internal pics posted by other members and I thank you for them!
I was thinking about using a mini pci card with 3g/4g and GPS to solve my problem like this one for Sprint Customers looks very nice and they claim android support. Could someone please verify the length available for the card from the socket to the mounting holes? It should be around 50mm but i cant tell from the pic.
I cant post a link so google

Then after more research I figured out that think I can get the GPS to work on the board. I found that the RXM-GPS-SG-T looks to be the exact chip they are using, the pin look to match exactly VCC, GND, RX, TX, RF, VOUT. So they are using an active GPS antenna (but could be modded for passive). They use NMEA-0183 or SiRF Binary output selected by a serial command. So we need to figure out if the TX is going to U39 making U39 the interface to the unit, or directly to somewhere else (idk need to see board) I hope i can attach my pic i made or maybe an admin can post it for me.
However the PCI slot might be just as hard to use, the pin 20 that has 3.3v isnt what we want, but it could be a software control to disable/enable the card. However we still need A+ on pins 2,52 (3.3V), 6,28,48(1.5V) and maybe 24(3.3V Aux) dependeding on the card. We could be dealing with a "Non Standard" connector, they are out there but most OEM's dont bother with them. More likely to find them on a Asus product ect. It's common for the SIM card to be powered by the PCI card itself and the board looks wired that way. I have 2 Digi International Mini PCI express Wifi/Cell Development boards and thats how they both power the SIM card. Pin 16 should goto Pin 1 on the sim card, 14->2, 12->3, 10->6 but maybe 7 or 8.
Getting the Power to it could be software or hardware. Looks like around U8 on the frontside could a Vreg setup, Or it could be as simple as putting in some 0 ohm resistors around R15 and R14. We also see that U7 is unpopulated on backside. So that leave us with U7,U8, R15, and R16 which could mean they are all part of the same circuit if they laid it out with any logic. TP1,2,and 3 also make me believe this is true, however they match up to LED_WPAN#, LED, WLAN#,and LED_WWAN#. I sure wish they match the power input pins, but that means all those missing resistors could just be for unpopulated status LED's. Like I've said over and over i cant tell ya unless i can probe around the board.
As far as the memory, yes its possible, I do BGA replacement at work. What I am afraid of is that the other memory chips look to be exactly on the other side and I'd be afraid of messing them up. I'd have to look at my jig at work and see if I could set it up without any problems.

I'm no electronics expert but I dabble. I'd be interested in internal GPS and a memory boost. I'm pretty confident in my soldering skills and would try something if directed by someone smarter than me.

This is something I am very interested in. Any new info on this?

I sadly no longer own a G tablet, wife thought it was to heavy to read books, and hated the screen. I cant argue with her on either of those points, so we returned it. However I got the ok to buy a referb on if i can find one, but when I did at my local store i showed them the paper and they told me they dont sell that stuff there and send me away. I talked to 3 different people too basically all told me to go f off. I even tried another time with the 7" they sell same results. I dont know why it gets listed on the website if they wont sell it.
Not to get sidetracked, but i even did by the proper bga fittings to solder the ram chips too lol..
So no its probably not going to go any farther from my stand point, if anyone wants my help I still read the forums everyday.
I'm just gonna wait and see what comes out in the future that XDA gets behind, because I'de never buy anything that didnt have an active community here.

IF you were looking for a reader fo rher mainly, you should've really gone with the Nook Color... eInk devices are good too IF you don't really need good PDF support and/or need it to read more complexly formatted documents, e.g. technical manual, mathematics texts, etc. i.e. eInk is best suited for ficiton and other simply formatted documents, but it VERY readable except in poorly lit conditions where you'd need external lighting of some sort.

Very true I should have bought her a nook, but now she doesnt want it because its not powerful enough for her needs imo. She also wants to login to her school (blackboard) and be able to use overdrive. Plus she likes dungeon defenders and I dont think that can handle it. We are just gonna wait it out and see what comes along, mostly cause we have our first due next month, so trying to be frugal.

Yep, you'll want a full blown tablet then and I suspect that the NC would be too much of a bother to get setup for her for what she wants it for...
All the 10" tablets are fairly heavy too, so you'll probably have to stick to looking for 7/8" tablets and I suspect Tegra 2 or multi-core cortex-a9 SoCs from other mfgs... not much in the way of 7" ATM other than the elocity a7 (was c. $300 around xmas), but it's not very hacker friendly and I don't know if they ever got the USB port to run in non-host mode... probably best to not even look at it...

The g Tablet would, as many have already said, be a great tablet if it had gps mainly and increased memory. Adding pci-e would be even better. I would be extremely happy with the addition of gps. I would be very tempted to allow somebody with expertise and high level of confidence of success to experiment on my tablet.

GPS+
Just bought my Gtab yesterday. As you know the stock Roman/UI sucks big time. I installed Clockwork followed by CyanogenMod 7 and what a difference. Anyway I looked on the web for a dock and it seems there is a Chinese version of the Gtab that has higher spec's including GPS. It would seem logical to assume the U.S. motherboard has the same circuits built in. Who knows what's possible....

It's too bad that more people don't feel like tearing up their electronics to start soldering things to them.

tablets with sim support?

i searched through the internet but there wasnt a solid answer to this question i could find.
the question is, which tablets have sim card support and if so how can i tell if the ones in retailers are different from ones offered from carriers.
like are there 2 models of galaxy tab 2 10.1? one with sim slot and one without? and could someone compile a list of all the current and popular tablets with sim card slots?

A tablet that does phone and uses AT&T or TMobil (assuming you're in the US) has a SIM slot. The SIM is used for the phone portion of the tablet on GSM phones. If the tablet doesn't have a phone, or it has a CDMA (Sprint, Verizon) phone, it has no use for a SIM card.

Well, of course. So the question would be "which tablets include a phone device ?" Nice try for an answer, dude ! BTW, it's not absolutely exact, as I'll explain below.
Ok, then, most SMALL tablets (7" or less) generally include a SIM slot because they allow you to phone without you looking as if you stuck a frying pan over your ear. This includes for instance the HTC Flyer and all Samsung Galaxy Tabs, just to cite the ones I know for sure, but of course there may be many others.
Classic "large" (10" or about) tablets can have a SIM slot too, even if NOT being able to phone. The reason is they allow 3G networking. If we are to cite another example, there is one on some Asus EeePads (not all models, so be careful when choosing).
Now the Eeepad is a bit special, as it has a true PC processor instead of most other models scaled-down 1 GHz ARM phone processors (the same my good old HD2 has already), and when you attach the separate mechanical keyboard to the tablet, you also get classical USB ports, allowing you to add a 3G dongle in case you bought a SIM-less model.
Apart form the Asus that's a bit out of the crowd (though not being more expensive BTW), you'll then have to check for the SIM slot when looking for a tablet.
Your question is of general interest IMHO. It wouldn't be a bad idea to keep a list of tablets with SIM slots to help people choosing, either here or on a dedicated topic, maybe put elsewhere (though I can't find where right now).
Now if you'd ask me which tablet I would choose if I had to, I'd answer "none" at first thought. The reason is, I do need a mobile device, but it has to do ALL : phoning, taking notes and noting down meetings, firing alarms, email and web browsing, remote access to the company's billing and accounting software, and my Word and Excel documents handy. And all this, of course, has to be with me all the time.
So, of course, the 4.3" format is just perfect. So why would I want a tablet ? The answer is just "I don't want one. Period". Now, why would I would want one anyway ? Well, maybe because it would be more confortable to show documents to other people, or just to get a larger workspace, after all.
So maybe the 7" format would be just fine. This, plus the fact it's able to phone, and the special stylus, always made me think about the HTC Flyer. Because I love my HTC HD and HD2, so I may stay sentimentally linked to HTC, so I probably won't be absolutely neutral here. There's also the Samsung galaxy Note, why not ? But if it's just for a larger phone with a stylus, is it worth the change ? Well, maybe for the stylus. The 7" tablet also still allows to phone whithout looking completely weird, though the limit is reached there IMHO.
Anyway, the point is, I want only ONE device to do ALL, and I want it with me everywhere and every time. That's why my HD2 is always in my belt pouch. I wouldn't want a phone PLUS a tablet to bring along. That's why I'm not really considering buying one, despite I really miss the stylus, as I often have to draw sketches and using the finger is just way too imprecise.
Now there's an interesting outsider, and it's once again from Asus : they threw some weird concept, a tablet containing a detachable Android phone ! All documents automatically synchronize when you stuff the phone into the hatch behind the screen, so you can actually always have the exact same and up-to-date documents on each, allowing you to bring and use any of them (or both !) according to what you're going to do and where you're going to. A concept at least worth a look IMHO.

Very good input. The truth is i'm a sales rep at TigerDirect in Canada. And whenever a customer asks me if the tablet they like has sim support, i'd have to give them a general unsure answer. It's unfortunate because not all tablets have it, and the specs on most sites never really specify either. Furthermore, it's not very realistic to open a sealed box to check if there is. Especially if the customer might not buy. I think it'd be great if everyone on the forums contribute and compile a list of model numbers of tablets that contain a sim card of some sort.

as a user ot the samsung galaxy tab 7.7 i would recomed your customers one of the 7" tablets there are wlan only and wlan/3g devices for each model. with a 3g module it allowes you to send sms or use it as a general mobile phone.
the bigger tablets only use the sim for a mobile 3g internet connection not for sms or phone, like the 10.1.
the wlan only version of the 7.7 is the gt-p6810 and with 3g its gt-p6800.
in canada the tab should be available very easy, but in my country i had little problems to get one of the 7.7 (the old ones 7.0 , 7.0+ , 7.0 2 are easy to get)
because apple sued samsung and said that the 7.7 looks like an ******* ipad.

Oh, maybe we should launch a contribution to offer Apple staff some glasses ?
OK, you did sum up what I thought : 7" tablets either allow phoning or are WLan only, and 10" tablets or bigger are either 3G or WLan only.
Each maker apparently offers both, for the same generic model number, so customers (and sellers) have to be vary careful about small details printed on the box and/or small sub-numbers in the model reference that may help finding more information on the web (preferably on makers' websites rather than half-informed resellers').
It's quite a puzzle, so maybe opening a Wiki here on XDA to list the "good" references could help people sorting things out.

OnePlus 7 Pro microSD Capability

After seeing these adapters listed online it got me wondering... although OnePlus definitely says the 7 Pro has no microSD support, are there possibly still actually hardware pins in the phone available for microSD use with the appropriate trays? My gut says these eBay sellers are probably just using default descriptions for these SIM trays and aren't alluding to functionality that wasn't included, but I figured I'd ask around for someone who may have seen or done a teardown to confirm.
Wishful thinking? Yeah absolutely. To me at least this definitely seems like the kind of thing that could have possibly just been default hardware included with the SIM tray module used, but was something OnePlus decided not to use/advertise due to UFS 3.0 being so much faster and even changed out the SIM tray to disable it completely physically.

That's pointless, even if possible

No.
It's not a hybrid SIM socket. Only room for two nano-SIM cards.
Trays that support a micro-SD and a nano-SIM are larger.

I've been wondering about this as well. Is using one slot for a Sim card and one for an SD card possible?

No! It's not a hybrid slot.

Ok I give up lol
Thanks

One more kick at the can.
Does anyone know of any product that exists for the OnePlus 7 pro similar to this iPhone one that adds SD card functionality built into a case?

I went ahead a bought a flash drive with USB C built in on one end and USB A on the other and I just carry it around with me now in my pocket. I honestly think this is the better option if you're trying to carry around extra storage and it's simple.
