The following steps should work for most CDMA Samsung devices running Android.
The first thing you will need to do is ensure that 3G/LTE (if you have an LTE device), voice, and text messaging are all working properly on your device. To do this, a Carrier Wipe, and Profile & PRL update are required. Please follow the steps below. For a number of these updates you'll need your Master Subsidy Lock or MSL--this is a six-digit code provided to you by Ting in your activation email; you can also find this information in Device Settings in your Ting account online:
1. Carrier Wipe
NOTE: A Galaxy Note II (2) running Android 4.3 may reset to factory defaults after a carrier reset. Back up your device first!
*for 4G LTE devices, no further action is required*
Once your Samsung device is confirmed to be activated and you have voice, text messaging and 3G data working, you’ll need to manually program your 4G WiMax settings to be able to access 4G data speeds.
Open the dialer
Dial # #3282# (# #DATA#)
Enter your MSL (a six-digit code provided to you by Ting in your activation email) and touch "Ok"
Press the hardware menu button (The page button located on handset in the bottom left corner of the device)
Touch “Write RLM”
Enter "mvno102.sprintpcs.com" and touch "Save" (Note: It will only say "Realm: sprintpcs.com" in this field)
Once the phone restarts, assuming you are in a 4G capable area, you should be able to use 4G data.
If you have problems during this process, there may be some additional configuration required. Please take a look at the steps outlined here. If you have tried all the options and are still having problems, get in touch.
Completing Activation on the GSM Network
Before beginning these directions, insert your activated Ting GSM X1 SIM card.
Go to Settings
Tap the Connections tab if your device has a tab view; if not go to step 3
Tap More networks
Access Point Names
Tap the Menu + icon to add a new APN
Enter APN settings
APN type: If there is a free form field, enter the following exactly as written without spaces: default,admin,fota,mms,supl,hipri,internet,dun
If your device has a series of check boxes rather than a free form field, check all the boxes that correspond with the values listed above. For example: your device has checkboxes for default, mms, supl, wap and ia. Check only default, mms and supl.
