Dual Sim?

Anyone know if I could use two sims simultaneously? I'm thinking of buying this phone to put a data sim and a pay as you go voice sim in.

Yes you can have two SIM cards simultaneously.
What you will need to do is:
Insert the Pay as you go SIM card into the SIM slot and the Data SIM card into the microSD card slot. To be able to do this will need to get a special code from T-Mobile called the SD-SIM unlock code.
Very important to use the Data SIM card into the microSD slot since this will give you better speeds than if you insert it into the regular SIM slot.

LOL. That was hilarious. The moment I read data SIM in the sd slot I started laughing

I've always wondered about all those dual sim adapters you see on Ebay. This One, for example claims to "Auto Switch" to allow incomming messages and calls from both cards at once, and manual switching for outgoing. for $7, might be worth a shot. Only downside is having to cut up your sims, but there are others out there that don't require this.

[Q] HTC Merge - sim wont work

I just bought a merge off ebay and its a US Cellular. I can not get my sim card to work in it (Mobile Network is uncheckable)
This phone is a replacement of my old merge which broke, they have the same model numbers on the back and everything.
Any ideas of where to start so i can get my GSM/sim to work in my new phone?

have you tried your sim card in another US cellular phone to isolate the problem, as in to see if its the phone thats messed up or your sim card (assuming they use sim cards, I thought they were CDMA?). If it doesn't work in another US cellular phone, odds are your sim is messed. Anyways I'm not too familiar with US cellular but maybe there is a block on the phone? Was the sim card you were using before a US cellular sim or are you coming from another company?

the merge is a cdma phone for us use. the sim card is for international use. if your trying to use the sim card for a local company it wont work...

You can use it with your sim after you sim unlock it and flash a different radio, you can do so using this guide. http://forum.xda-developers.com/showpost.php?p=16211361&postcount=117

[Q] Best way to transition from regular sim card to micro Tmobile US LTE?

I am about to get the phone once it is processed. I am using an old galaxy s 4g with a regular sim card. I also have a 2 year old unused micro sim card. I wanted to know if it's best cutting the regular card to a micro sim card or activate the old unused micro sim card. Or do I have to get a newer micro sim card from t-mobile. If I do either the first two methods, will I still have lte even though they are not the newer sim cards? I have read that even if you activated the newer sim cards at a tmobile store that people didn't still get 4g(Lte) but instead got the H/H+. Others are saying that the phone or the account needs to be provisioned. I am under as an added line under my mothers account which is only a few months old if that matters. Thanks in advance.

T-Mobile doesn't need any provision. If I was you, I would personally just get a new Micro SIM, you ensure that you have the newest and latest SIM card which will ensure that you'll have the best possible experience in LTE data and cellular signal.
Call them up and they'll give you a free SIM replacement in the mail, or you can go to the store. Very easy to do.
If you did cut your sim card into a micro sim, you wouldn't get LTE with that old of a SIM card. Enjoy your phone.

To get LTE you will need an LTE enable/capable SIM card, so get a new one from Tmobile

Help - Unlock Carrier tool

I have a polish sim card which works fine with my other Iphone, when i insert the same sim card to my nexus 5 it can't register to any carrier !
Why is that, is there any solution for this bizarre problem ?
Thanks

You tried the sim with an iphone (works) and Nexus 5 (doesn't work). Did you try the sim in a third phone?
The Nexus 5 cannot be carrier unlocked because it was never carrier locked.

I don't have a third phone. Do you think that I should flash another radio ver. on the phone?

The Nexus 5 detects the sim card? If it does detect the sim card, I think your iphone's imei is somehow tied to the sim card.

What does it mean?
And how can I resolve it?
I would really appreciate any help ?
P.s.
Apparently a different sim (vodaphone) doesn't work in this phone either.
???

Has the vodaphone sim been activated?
If both sim cards do not work in the phone and the phone can see but not connect to networks, it may be possible that the phone is blacklisted? Is the imei correct?

That's friend phone....so....
He said that the sim (which doesn't work right now) worked before. I don't know about the Vodafone sim.
How can i find out that this phone is in the blacklisted?
Thanks again,

You can check the imei here: https://swappa.com/esn
Since the vodaphone sim is not active, it is not a good test of the Nexus 5. It would be best to try an active/working sim in the N5.

1. How can I know if my phone tied to the sim card ? (you mentioned it before)
2. Do you know this website http://www.imei.info/
Thanks

I don't know that site but the swappa site will tell you if the phone is blacklisted.
The only way to tell if the sim card is tied to the iPhone;'s imei is to try the sim in another phone to see if you can connect to the carrier network. In the USA, AT&T tie their prepaid sim cards to a phone imei.

As I mentioned before the sim card worked fine with my iPhone.
But the "fishy" story here is that the Vodafone's sim card doesn't work as well.
So it might be a blacklisted issue.
Your thoughts?

Did you check the imei on the swappa site?

Note yet

I would check the imei to make sure the imei is not blacklisted and does belong to a nexus 5.

I updated my friend to do so.
Thanks

Can I unlock a phone without a sim card?

I requested a unlock code from ATT for my Lumia 640, surprisingly it was approved in less than an hour, I have the code but I don't have any kind of sim card that fits the phone is there anyway to enter the unlock code without a sim-card, I read any sim card should work. anyone know?

Unlocking can only be done in the AT&T network coverage region. Without a SIM card in the phone, it is not possible to connect the phone to the mast.

Ok but what I read is not to use the AT&T sim card only a non network sim card would trigger the entry for unlock code, but that doesn't add up if the phone needs to be connected to a ATT&T tower, which I assume there is one where I am. Actually a non network sim card is showing as valid but I get because the phone isn't unlocked yet it won't work. So it looks like I need a ATT&T sim card than, does that mean I would have to sign up for service with them? Or do I just buy a ATT&T sim card on ebay and unlock it to use on the network of my choice? Thanks

For specific questions, it is better to contact the mobile phone operator directly. Especially since you have an easy contact.
