I'm going to US for 5 days but the phone is just for emergency use. I go to US less often these days so I don't want to deposit $100...but Roam mobility SIM card costs $20 that's a bit too much...and I have two phones too...
Looks like T-mobile is better deal but I can't get the t-mobile SIM here quick enough before I go.
Hopefully airport may sell T-mobile sim?
