It's not possible to start my tablet
Solution 7 of 7: Your tablet is locked to EE
If your tablet is locked to EE and you try to use a SIM from another operator, the screen will tell that your SIM is invalid.
Call customer services on 150 (from an EE phone), 07953 966 250 (from other phones) or visit My EE to have your tablet unlocked.
