T-Mobile 4G network coverage SIM card upgrade

Do you hvae a T-Mobile 4G-speed phone and want better network coverage?

Here's a free upgrade I learned today from T-Mobile for my T-Mobile Google Android HTC G2 phone.

The problem

Some older 2G Mini SIM cards are having network coverage problems when put in 4G-speed phones.

You may see error icons like an "X" on the network coverage icon in the upper right of the Android notification bar. You may see error messages like "Cannot connect to network" when you try to call someone.

The fix

Go to any T-Mobile store and get a free SIM card upgrade.

Do you have an older Mini SIM Card?

Take out your Mini SIM card.

Does your Mini SIM have any writing on the side with the gold areas?
