Hi I had my phone unlocked by sprint and got a confirmation email saying my device is unlocked for international use. I was told by the sprint representative that there is no way in testing if the phone is unlock when I'm in the US. Is this true? or is there a way I can test the phone if it's unlocked, I do have an international sim card from Jamaica but I want to test if the phone is unlock before I leave the states.
borrow a friends SIM?
this belongs in the Q&A section not general.
this has been answered already. you can test if its unlocked by putting an att or tmo sim card in. if there is no sim card error when you boot up.. then its unlocked.
the sim error would be in the status bar. "invalid sim". if you see invalid sim.. it's not unlocked, despite what sprint says.
if it IS unlocked properly.. that still doesnt mean that you can use tmo/att... itll only pic up a gsm signal when using an international sim.
I have a sim card from Jamaica, I am going to try it when I get home but I think I forgot to change the mobile network to GSM when I inserted the the international sim card.
Just got back from my trip to Jamaica and my phone worked great with the international sim card. I had the sim card with me in the US and it didn't work when I was here but as a landed in Jamaica I put the bad boy in and I had service only down fall was I couldn't get data. So the unlock from sprint do work internationally.

i ran lockiwiz and I don't have any other sim cards to test it out but how can you tell if the phone has been sim unlocked?
anyone????????????????????????
The only way is to use a SIM from another provider.
I you don't have any friends who trust you enough to loan you a SIM for 5 seconds then try going to a Mobile Phone shop and telling them you are thinking about switching providers and your phone is supposed to be SIM unlocked but you want to be sure before you start shopping around. Most likely they'll be happy to help you test your phone with one of their SIMs (hoping to get a new customer).
i just recived my unlock code from tmobile and i want to test the code and see if it unlocks my phone.
where can i get a foriegn sim card?
is there a website? or can i unlock it without a foreign sim card?
again, i have my code
also, lets say, i am in germany.........
and i get a sim card from over there.........can people still call my US number? or will that change?
is this legit?

you dont need a foriegn sim card,
all you need is an "unsupported" sim card... any non Tmobile sim would work
once you have it in the phone and power on you will get a message like
"Please input unlock code"
punch in the code, then it will "find" the network the sim is attached to... so if you use an at&t sim card it will register to the att network in about 30 secs
.....
so mainly is
1. use an unsupported sim card
2. enter unlock code
3. verify it connects to the unsupported network (at&t since those sim;s are easy to get)
4. put your normal simcard back

got ya, thank you for your fast reply, i thought i could do it that way, but just wanted to be sure.
"

the number is tied to the sim
if you put in a sim card from another operator you get a new number
and people can't call the number of your old sim
even if you get a dual-Sim holder and have 2 sim in the device granted it support it
most places the rules apply that if other people call your USA number
while you're outside
they only pay for calling you in USA
and you pay for directing the call from USA to what ever country
you're presently in
if this is fine by you you don't even need to unlock it as tmobile would have
roaming agreement in many countries in the world but at a high cost of cause
I have tried every code mentioned, in here, that was successful for others but not for me.
I started by buying my Galaxy S4, out right, at Walmart for use on Family Mobile. Poor signal everywhere except in my house. The phone has T-Mobile support as far as towers go. After about three weeks I had my phone number transferred to Straight Talk and they sent a SIM card for use with AT&T support. The phone was purchased as an unlocked phone, I did all the codes in this forum to check and sure enough, it is supposed to be unlocked, BUT, every SIM card I get from Straight Talk gives me "INVALID SIM CARD" when I boot up the phone then a black screen comes on with a subdued color message saying, "Sim network unlock PIN" and all the help from Family Mobile, T-Mobile, Straight Talk, Walmart and AT&T, have not helped my situation. I can't write a new APN and store it because I have an invalid SIM card. I have tried the service mode and did everything mention in these forums but no luck so far.
I really like the device(my NOT-Phone) but it does not function as a phone. Can anyone help with this one?

No warranty in Walmart?!
If it connects to T-Mobile towers out of the box, can you borrow a T-Mobile SIM from soneone and go through the SIM unlock procedure? I'd do that just to make sure it's SIM unlocked. Then try Straight Talk with whatever APNs they use. Do this on stock and once you can confirm you get that far and it's working then go crazy. Good luck.

If I put the original, 1st SIM (Family Mobile) that I bought, back in, I do not get the Unlock Sim code message but I also do not have service because I already had the number ported. I've been that route. I tried the APN routine but it won't save because I don't have service with that SIM card. I go into the unlock routine through the service mode and it says it's already unlocked. Any Sim card from Straight Talk gives me Invalid SIM.
I'm going to return it to Walmart and try another phone.
According to one of the mods at Android Central you can switch a 900v to tmobile and get full lte speed by manually changing the apn. No need to switch to band 4. Is this true? Has anybody done it? I would love to stick in a tmobil3 sim and try it while retaining the option to go back to vzw unlimited data if tmobile signal is unsatisfactory. Thanks for your help!
900v on Tmobile
I have tried my wife's t-mobile $30/month no contract Sim card in my Sm-900v and it works great. I got 4g lte and the down load speed was 43mb. It was faster then my Verizon speed of 15mb. The t-mobile Sim card automatically stored the apn on the phone but if it does not just manually add the apn.I did verify that my band 4 was already enabled.. Band 4 has to be enabled to use on T-Mobile BUT you do not have to disable band 4 if you want to go back to verizon leave it alone. For what i understand Verizon enables band 4 out of the box so just get a cheap pre- payed card and try it out for a month. Hope this helps you out.
So no need to call for unlock code? Tmobile guy said they woildnt give me a sim without it

I bought my phone used so I do not know if it was factory unlocked.. 2nd you can just go to any store that sells t-mobile sim cards and buy a prepaid Sim card. I bought mine online from t-mobile (out of convenients) they mailed it to me.. no need to go to t-mobile store. Again buy a cheap Sim to test on your phone. Worse case if your phone is carrier locked you will only lose $30. Or if you have a friend with a different carrier try there Sim card to see Iif your phone is unlocked or not. Also you can just call Verizon customer support and just ask for the unlock code it's free.
Where does the code go? Is there a setting where?
As soon as you install new sim card and reboot phone first thing it will ask you for a unlock code.. you will enter code on same screen. If it does not ask you for a unlock code then your phone is not locked then enjoy your new tmobile phone.

Thanks for the 411.
No problem hope it helps you.
Hit the thanks button if i helped you
Thanks in advance for your time.
I consider myself somewhat savvy. I have searched all over for an answer before asking:
I bought a SM-G870A and I have tried putting an H2O SIM card with no unlock screen. I tried two other SIMS with no unlock screen. I assumed it was unlocked.
I tried selling this phone to a guy who was going to use it in Mexico and told him it was not SIM locked. He tells me that when he puts his SIM card in it asks for an unlock code.
I am lost as to why it would suddenly ask him for an unlock code but all my SIMS did not. I have not been able to see him try in person yet.
Why would I be able to put SIMS in the phone and not get asked for an unlock code. I thought that meant it was unlocked?
Thanks for the help!
I just went through this "sorta" thing when I unlocked my t-mobile s5. I took out my t-mobile sim and put in a metropcs pcs sim and got no unlock screen upon reboot. I put in a cricket wireless sim and upon reboot I got the unlock screen, which I quickly put in my unlock code.
I'm assuming since metropcs is owned by t-mobile, that is why it didn't ask for an unlock code.
Is h20 owned by at&t, if so, that could be why the phone didn't ask for an unlock code when you put in the h20 sim

Thanks for the feedback. There could be something like that going on.
h20 uses the ATT network.
I tried a Simple Mobile (T-mobile) and no unlock code prompt
I tried a US Cellular LTE card -- would not connect to network -- no unlock code prompt
I tried a Verizon LTE card -- Same as US Cellular
I am stumped as to why this would happen. I would think a locked phone would not accept those cards without an unlock code prompt.
