I unlocked successfuly my tmobile g1 coming from usa, but now I have no signal and unable to register on network.when I go in settings,wireless control,,mobile networks.when i ask for available networks i have this error message:"error while searching for networks".even when i choose select automatically i have this:"your sim card does not allow a connection to this network".we have GSM, GPRS, and EDGE in my country.Do you have any idea?thanks!
It's your SIM card being locked to a specific network. You might have to contact your vendor.
I don't understand,my sim card locked?I don't have pin code.you are talking about my foreign sim card(non tmobile?)could you explain more?
I don't know why either. I just know that is what happens. I had the same problem with my SIM too when I went on vacation. But I didn't bother trying to fix it. Since I brought the local SIM to use because I didn't want to pay the international rates.

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
Hello everyone,
I have a T-Mobile Wing which I want to use with an AT&T prepaid SIM card. I called T-Mobile and received the SIM unlock code, but with the AT&T SIM inserted my Wing is unable to connect to the network (it simply says "Searching..." in the left corner indefinitely).
I understand that this device does in fact work with AT&T service so I am a bit mystified. Perhaps the solution is staring me in the face and I am just too daft to see it. If anyone could shine some light on this for me I would greatly appreciate it.
Is a 3G sim card? Might not work on an Edge phone
lol you have to configure the network for it to work. Try the cab in this post:

Hi I recently unlocked my G1 with a code, I had service. after I had to activate the phone but my sim card wasn't provisionned for data.so I turned off.Now when I put sim card the phone don't see any network,it don't ask me unlock code.I have no ideas please help me.
do you have tmobile sim? you shouldn't need a code.. but if you dont have a data plan it shouldn't matter anyway bcuz you cant do anything with the sim... basically can only use wifi and if your device is rooted you dont need a sim, sorry if i mis understood the question
Once you unlock your G1 from T-Mobile, it stay unlock. You can use any SIM from any network, but you might have to setup the APN for your vendor. (IE: AT&T, Sprint, etc...)
As stated by ldrifta if you don't have data service from your vendor, you can only get internet (online) using wifi.
So, in order for you to get provision you will have to get with your vendor to pay for the service.
I have good apn settings for my vendor mcc,mnc,apn and so but I still don't have service. I'm anxious for that, or I need to activate first using wifi before having service?
Since you have already unlock your G1, my suggestion is to get the data service. So you can start using it.
I tried a friend sim card provided with data service but it sill don't see any network,no service.Do you have any idea about it.Thanks
Go to Setting >> Wireless & Network >> Mobile Networks >> Network Operators
And select your vendor network you supposed to be on. That should registered your phone on your vendor network.
ok I will try
I tried to use my Sprint S4 while in New Zealand and found that I had to manually reconnect to the local Vodafone network several times a day. Most of the time I was denied a connection with a message saying that the SIM card was not permitted on the network.
Sprint triple checked that everything was OK on their end and kept saying the problem was with Vodafone, which may be entirely accurate. However I don't want to travel again and find out that there is a problem with my SIM card or the phone.
Any problems like this in NZ or otherwise internationally?
Any ideas on how to test the SIM card or other functionality?
I'll probably ask Sprint to replace the SIM card as a precaution.
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.
