Opt told me Malcolm Gibbs that if I transfer every thing over from TMobile i would not have any problems my number would transfer over successfully however im having a lot of problem right now i can't make phone calls because of sim card activation the people from Opt with customer care sometime i can't understand because of there strong accent right now i can't make any phone calls because the number does not go throw a customer care person did something on his end he said wait 10 minutes i still can't make any calls

Desired outcome: i want my phone to work properly i want the my phone to have the right number and voice mail
