Hi well i have the lg thrive im on the 50 unlimited talk and text plan and i pay 25 for data so i pay 75 a month. And i will be going to mexico next tuesday to tijuana and ensenada i live in los angeles so its close. And i wanted to know if my lg thrive will work? I heard that at&t go phone roaming in mexico is 25 cents the minute to make calls. I wanted to know if this is true? And if it is how does it work? I berly added money my phone 3 days with my credit card by calling 611 ago i put 75 dollars on my account and it worked but i wanted to know do i put more money or what? Because when i dial *777# i get a message saying my account balance is $0.00 but im able to talk and text all i want and use the internet on it . So i wanna know since im going to mexico should i add more money like another 25 bucks? Because since im here in the US im able to take advantage of the unlimited calling but since they charge 25cents the minute in mexico which im willing to pay and it says my accout balance is on zero should i add more money? Sorry if i dnt make sense its just that im confused and i really need help cuz i dnt have time to buy an unlocked phone for use in mexico and i dnt wanna buy a mexican phone because im only going for 2 days im willing to pay roaming charges as long as my lg thrive works over there. I wnt be using data while roaming i only need it to call back to the US thanks.
