How to SIM unlock the HTC Vivid and add T-Mobile’s access point

I recently purchased a HTC Vivid on Craigslist while on vacation in California (my home state I might add), fully aware that the phone is sold to operate with AT&T service, but I knew the good guys at HTCSIMUnlock.com would be able to help me get this phone unlocked and ready to run with my T-Mobile SIM card.

The process is simple, contact HTCSIMUnlock.com using their website, provide them with the IMIE number to your new/locked phone and follow the steps below. Please note these steps were used for a HTC Vivid and unlocking other phones may vary.

Insert T-Mobile SIM card and power on the HTC Vivid.
Unlock the phone using the circular slider.
Enter the code received from HTCSIMUnlock.com when you see the prompt, ”Enter the SIM network unlock PIN” and press enter or done.

At this time you should see a successful message and the HTC Vivid will restart. After the phone has restarted, go to Settings, select Mobile Network, select Network Operators, press Search networks (T-Mobile & AT&T should pop-up) and then select T-Mobile. Your phone will begin registering with T-Mobile’s network and will notify you when this is complete. You may have to reboot one more time, but other than that your phone has been configured for cellular use with T-Mobile. Next, you will want to add T-Mobile’s Access Point Settings so you can use your data plan on the Vivid. Go to Mobile Network under Settingsand follow these steps:

If there is a T-Mobile APN, touch it. If not, press the Menu key, and touch New APN.
Verify and update the following settings for the Data APN:
- Name: T-Mobile
- APN: epc.tmobile.com
- Proxy: <Not set>
- Port: <Not set>
- Username: <Not set>
- Password: <Not set>
- Server: <Not set>
- MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
- MMS proxy: <Not set>
- MMS port: <Not set>
- MMS protocol: WAP 2.0
- MCC: 310
- MNC: 260
- Authentication type: <Not set>
- APN type: <Not Set>
Press the Menu key.
Touch Save.

Afterwards, you should be all set and your phone will be running on T-Mobile’s network. Thanks again to HTCSIMUnlock.com for the assistance!
