Hello.

You can try to unlock this phone via writing IMEI Certificate, Note, after writing IMEI Certificate, phone's IMEI will be changed to the IMEI from the IMEI Certificate file! The procedure is the next:

1. Install the latest Software version (Software).
2. Install the latest drivers (http://octoplusbox.com/files/drivers...ile_Phones.exe).
3. Root the phone.
4. Read backups of Security, EFS and QCN.
5. Make Wipe Security.
6. Write IMEI Certificate (try to write IMEI Certificates for GT-S7275B/T from the Support Area).
7. Insert SIM card, wait 5-7 minutes and try to find and select network manually.

does this mean each time you put a different sim card you have to look for the service manually.

No, this is only to check the network after writing IMEI Certificate.
