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

How come Sprint doesn't use a sim for their LTE? Is the sim even necessary or is to bring global usage to the Verizon version?

The SIM card is used for 4g. 3g and voice is over the cdma radio. And sprints does have a SIM if I'm not mistaken it's internal tho and cannot be accessed.
The biggest problem with the "non-removeable" sim setup that Sprint uses is you can't just pop it out & stick it in another phone.
I do this all the time with my VZ sim card.

thats for sprint? it looks like verizon its all handled through the sim for both lte and 3g.... right?
As far as I know its just the lte that needs the SIM. Now of course the phones are made to not function w/o them but I'm pretty sure it's only the 4g that actually relies on it
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.
Hi everyone,
I've got R7plusf with CM-13.0-20160407-NIGHTLY. I have two nano-sims. The second slot is obviously not supporting 4G, I can clearly see it on the speed-test and also on the screen - there is only 'E' showing for the second slot, while there is H+ for the first slot. I've double-checked the settings - LTE is preferred for both slots. Does anyone have the same problem? Does anyone know how to enable 4G for the second slot?

Second slot only supports 2G no 4G

Is it so? Here it is said otherwise.
On the official Oppo site it is said "4G Dual Sim" - that makes me think that both slots are supposed to support 4G.

Sorry to clear it up you can not use both sims as 4G. If you use sim 1 as 4G sim 2 goes to 2G and the same with sim 2 as 4G sim1 goes to 2G.

Wooohoooo!! Now that works for me - thanks a lot!
The problem was I could not set up the second slot to use 4G before I specifically set the first one to use 2G.
I though once you've chosen the sim to use cellular data it has the priority, but that was not the case.
Anyway I am happy to have it solved now - thanks again, 2007jchill !!
I have a question about dual sim model. Do both sim card can work simultaneously eg. 3G like eg Xiaomi 5?
Most of dual models work with mode (2,3,4)G/2G or 2G/(2,3,4)G only.

One SIM must be in 2G. The other can be 2G/3G/4G.

Is that 2g , so no data phone only or just gprs?
I meant 2G as in phone or SMS only.

Any idea why is this limitation? I was trying to see it to LTE mainly to put that in VoLTE for calls and then realised either of the SIM only can be set to LTE.
On the XZ, I have sim1 on 4g and sim2 on 3g.

I've asked the same question to a Xperia rep. when I've purchased XZ dual in Hong Kong.
Both slots are 4G speeds, but if both slots are in use; highest speed of one slot is 4G and other limited to 3G max
They don't have 4G/4G support yet...
Hope this helps.
Well I was going to start a new thread, but this seems like the correct place to ask:
So if I have one sim dedicated to calls/text and a second sim just for data, the phone should operate the same as if I had only one sim which can do both phone and data?
Also if both sims are capable of handling calls, can i deactivate the phone of one sim card but keep the data active?
Can anyone let me know if the S8+ Dual Sim is 4G/3G as Australia is turning off all 2G networks.
Thanks
It's 4G/3G/2G (SIM 1) + 4G/3G/2G (SIM 2).
TL;DR: LTE/LTE.
Pretty sure that SIM 2 is GSM only

2nd sim is 2g/3g on my s8+.

Both SIMs are 3G and 4G, but you can use as 4G only one and the other one will be max 3G, or if you prefer can be 2G as well. This is not so relevant, since you switch the SIM cards for internet use (since you can not use both cards in the same time for data usage) it will change settings to 4G for the preferred SIM immediately.
