T Mobile Cell phone service

I looked at that flex pay thing....I liked it it looked like a good plan....cant remember exactly why i didnt go for that but i think it had something to do with getting internet service but as it turned out they had to be ordered completely separately anyway....
Im not sure why they gave us miami numbers but i know i have tried looking things up by my zip code before and there are always problems....we live in a tiny little town and the zip code doesnt register for some reason but still i told him my address in NC so youd think he would have at least given me a NC area code....anyway when i called them they changed the numbers for me to 919 our area code but then i tried calling the number from a friends cell phone to see if it worked and it did except i had to dial 1 + 919 + the number...and when i called customer service they were confused....I understand that if some one calls it using the 1 from within this area code it wont be long distance but the problem is this is the phone my husband will be using for work and try telling the contractors they have to dial 1 + area code when they call him....they wont do it and he will lose a lot of work....but i think that got fixed too cause i tried it from a pay phone and didnt have to dial the 1
so i will just try it from a few more phones tomorrow....
I hope it works itself out cause i have been nuts without my internet last couple months....
