AT&T is shutting down 2G by the end of the year.
Is there any dual sim Android phone that have two active 3G. I don't care about data, I just need two 3G voice line.
Thank you for any help.

If I lost my 4g SIM card, could I still operate my 4g phone with voice/3g with a SIM?
Lets say I swap the ESN on my phone line from a 3g phone, to a 4g phone, but I don't have the SIM for the 4g phone. What can and can't I do with the new 4g phone?

Nothing. You need the 4G sim.

If this is correct, then the SIM card is not just a 4g card, its a complete lock-down/control mechanism by Verizon.
So, then my next question is, why do they limit this to 4g phones? Why not all phones? Since the purpose isn't solely 4g security.
If I put my Verizon 4g card into a different Verizon 4g phone, does that automatically activate it on my account (similar function to ATT/TMobile SIM card), so what I'm saying is, there is not specific phone linked to your account, instead its a SIM card linked to your account. So, say I switched SIM's with Droid Razer with my girlfriends Thunderbolt, does it automatically switch activations/phone number/etc ?
I am pretty sure it works without the 4G sim. Because people used to take the 4G sim out to save battery I thought in the tbolt before it could be turned off via software.
ok, I think this answers a lot of my questions. Apparently, it is like a GSM sim

Swapping SIM's will change your activation automatically.
From what I've read, you can pop a Verizon 4G sim into pretty much any unlocked LTE capable device and have it work.
Now I'm guessing this is going to be a no, but...
I got an Airtel 3G Data card (specifically the Huawei E1731) when I went to India and unlocked it, if I remember correctly it kept swapping from CDMA and GSM signals. Now if I pop the Nano SIM I got with my iPhone 5 into this data card, (I'll try to make my self a Nano SIM to SIM adapter) is there any chance of it working?
I've also heard if things like the 4G sim being deactivated when you swap to a 3G device. But wouldn't putting it in a 3G device be the same as using the iPhone 5 with LTE turned off?
And is there any chance of Verizon messing with my data plan if I put the sim in the data card and start using it with my laptop?
I just saw a a video of someone putting a nano sim in an iPhone 4s and it working so I think this should at least work on the data card, still worried about the Verizon side of this.
Also I just remembered something about different frequencies, would the fact that the data card is from India affect my ability to use it?
Actually, I'm pretty sure Verizon SIM cards are only for their devices. I don't think they work otherwise

I've read from a few different reliable sources, don't have any links on hand. But its the phone that is locked to a carrier, not the sim that is locked to the phone, so as long as the device is unlocked and has the required hardware, it should work with that sim.
In verizons case, at the very least the LTE should work with an LTE device, I'm not sure about voice, 3G, and 2G.
In that case you wouldn't get 3G on other phones, since the SIM cards Verizon has are for 4G LTE only, their 3G networks are CDMA and thus built into the phone.
LTE is a GSM technology which is the only reason they use SIM cards at all

That is what I was thinking, but the data card seems to have both CDMA and GSM bands and when I pop out the LTE sim from my phone I lose all signal not just LTE.
Now what I'm thinking is that, since the SIM holds all the Account info, etc, not just 4G related things, that if I pop it into the 3G data card, (I've seen Iphone 5 SIM be put into a 4s and work) that it should work. That is if the Data card is compatible, which I'm not 100% sure on.
The SIM in a GSM phone holds all the account information. The SIM in a CDMA phone is for data only - the phone will work for voice/text without it. The SIMs are different software/wise.

That's what I initially thought but, If that's true than why is my iPhone 5 not able to use Data, voice, or text without the SIM inserted?
I'm not to worried about it not working, the thing I'm concerned about is verizon messing up my plans if I try using the sim in a data card.
Hello,
I'm currently on AT&T with an HTC One M7. I've had my fair share of rooting and playing around with this and with my contract ending in 2 months, I've been eyeing the Z3 as my go to device for the next 2 years and intend on buying it before my contract is up to just replace my HTC soon.
1) Currently it would be a hassle for me to call AT&T to get a new nano SIM card, so I guess that purchasing a cutter to convert my current one into a nano SIM would be fine? I wouldn't need to call them up to mess around with a new IMEI or anything assuming I'm basically using the exact same SIM card?
2) I've heard that the D6633 version (dual SIM) has full support for AT&T LTE whereas D6603 is merely only 4G. Can anyone clarify this?
Thank you
I have full LTE on AT&T. I just needed to have a nano SIM card installed at an AT&T store. There were zero issues.

I've also got full LTE on a D6603 on AT&T--speed leaves HSPA+ in the dust. Purchased directly from Sony store and registered as a new line with the guy in the AT&T store scanning the box for the IMEI code. No problems at all although it does seem to need a strong LTE signal. At home I have to switch network mode to WCDMA/GSM or it will constantly hunt between LTE and H+ with a significant battery hit.
I'm contemplating a purchase for a Mate 9 with dual SIM capability ( from Kogan Australia). It's advertised with dual SIM. For me, the secondary SIM would only add value if I can use it on 3G, while I keep the main SIM on 4G.
But in some documentation, the secondary SIM only supports 2G. Has anyone successfully used Mate 9 with 4G+3G SIM combination.

For sure....! I also think 4G+4G can work...
If the Australian version is the same as the European version it will support 2G, 3G and 4G on SIM 1 whilst SIM 2 will support 2G and 3G.

3G would be great on SIM 2. The problem I'm trying to solve is that our Australian telco ( Optus ) has severely degraded its own mobile network, to the point where we can't receive voice calls anywhere in our suburb. LTE used to work well, not any more. On the other hand, they improved somewhat on their 3G network. My wife is still in contract with cheap plan. So I could arrange a dual-SIM where SIM 1 is on 4G with another telco, while SIM 2 stays at 3G with the old telco. Things may improve for their network, or the company is going down, we shall see.
4G/3G is how it does it.
Both will support 4G but you'll need to put the switcher setting on your homescreen so you can switch quickly - you can't have both on 4G but both will support it. The other will be able to use 3G.
I use two sims, my primary sim is used for talk and texting and the second sim is for data.*
The data connection keeps on dropping to H+ or 3g with extremely slow data speeds. Is there anyway I can force 4g only on sim 2.*
P. S. I DON'T WANT TO USE THE DATA ONLY SIM IN SIM SLOT 1.*
Thanks
