When I web searched your problem I found you are not the only one but haven't seen any resolution yet.
In my area I would good to the T-Mobile office near Antioch/Brentwood Target because they tend to be quite helpful.
You could try T-Mobile support

Usually when this happens it means T-Mobile needs to reset your mail box. Contact them.

Check with T-Mobile about that.

  • Why does my iphone 5c keep saying invalid sim? I ordered an iphone 5c off line around October and it was used but when i received it i went to the store and bought a Straight talk sim card so i could use it through that company and it worked great but lately my phone will randomly say invalid sim and sometimes restarting my phone helps but recently it hasn't been helping at all…
  • My straight talk iphone 6 says that the number I have dialed is invalid? EVERY number i dial it says that it's invalid, but i know that its not. These are my saved contacts and i know that their phone isn't shut off. I have tuned my phone off and back on, i have taken out my sim card. I don't know what else to do, but i need to make phone calls.
  • My number is invalid number in viber, I have an Iphone 5s? When I want to setup my Viber on my Iphone 5s it shows an error that says "invalid number", every number that I put is an invalid number. What should I do?
  • IPhone randomly saying invalid sim? So I bought an iPhone 7 from someone I knew that was stolen. I paid 25 for it then spent 80 for a guy to jailbreak and remove the iCloud. He put something on the SIM card and told me not to take it out. The phone works perfectly but maybe after 2 hours it'll say invalid sim then I have to restart and it'll be back to normal. What should I do and I don't really have the money to get it checked out again.
