Problem after unlock procedure

hi peeps, i have put my o2 xda2 back into service and used the excellent unlock giude from this forum (itsme' guide) and unlocked my phone to try and use with a t-mobile sim.
Having run the v.1.6 on it, when i put my t-mobile sim card in the phone i get the t-mobile logo and 4 bars of reception however it wont allow to me to make/receive calls or sms etc any ideas on how to fix this or what the problem maybe?
thanks in advance
it sounds like tmobile sim is old.try sim in different phone and see if it has same problem.if so a new sim should cure it

[Q] Can't unlock phone, phone doesn't ask for Sim network unlock pin

I am trying to unlock my AT&T Samsung Captivate and I have followed the instructions in the reference thread for unlock/unfreeze for all SGS models. I tried both methods with SGS Unlock and ADB, as they both are supposed to do the same thing and as a result I got the same unlock and unfreeze pins.
After I got the unlock code I restarted my phone with a Fido Sim card but my phone doesn't ask me for a Sim network unlock pin and it just loads the desktop. My Sim card works in my other phones, so it can't be something wrong with my Sim. I also borrowed my sister's Fido Sim and still my phone does not ask for the unlock pin on start up and displays the there is no sim card in phone screen.
I'm hoping its not something wrong with the phone's Sim slot.
Does the Fido sim work in your phone?
It is possible that Fido is an authorized sim in addition to the AT&T sim.

[Q] 4g activation (region specific - colombia)

hey people, id would very much appreciate of someone could help me with this issue.
here is the deal:
i have moto X from CLARO (Colombia), on KK 4.4.2 (t-mobile firmware - SO NOT STOCK CLARO FIRMWARE)) , unlocked bootloader, rooted (soon with a non stock kernel). today i got in the mail a new 4g sim card (yay!!! 4g finally came to colombia what evs...). THE PROBLEM IS THE SIM CARD IS NOT ACTIVATED YET, see, along with the sim card i got instructions detailing how i should go about activating the sim card, which basically goes something like this:
1. dial *611# (USSD code), press send and wait for the options to appear.
2. in the options menu, dial the number 9, which should say "Sim 4g" and press send.
3. next the system will prompt you to enter the serial number of you new 4g sim card.
4.type in the 17 digit number of your sim card that's located in the bar code (this is on the plastic card that the sim card came in) and press send.
5. a message will appear telling you that the change has been done successfully, wait a couple of minutes until you have no signal on your current sim card and the switch to your 4g sim card.
ACTUALLY THE REAL PROBLEM IS!: whenever i dial *611# i dont get the 4g option, my theory i that because i am not on claro's firmware i dont get that option (but i do get all other options), or it has something to do with kit kat?.
i guess my question would be:
- is there a way to activate a sim card that doesnt involve taking it in to my service provider? (considering i have an unlocked phone i no longer have warranty)
- has anyone anywhere gone trough something similar?
-any ideas on a possible solution?
