I bought a phone to use on vacation out of the country. I know I can buy local sim cards in the airport, so that part I am not worried about. I wanted to activate the phone before we left, though--partly to make sure it works, and partly to play with it. So I wandered down to Walmart and told the girl what I wanted. She said I needed the 30$ T-Mobile plan (which is apparently only offered through Walmart?) Anyway, she said the sim cards were 25$ if I went to T-Mobile, and that if I bought the el-cheapo phone it came with a sim, and I could activate it, then move the sim to whatever phone I wanted. Does that sound right? Do you have to activate the cheap phone then move the simto get the 30$ plan? (Sorry if this sounds to dumb for words. I had never even seen a sim card before last night.) Thanks!
