Our USA SIM cards last 30 days from activation. If you’re staying for longer, you can go to a T-Mobile, Verizon or AT&T provider to recharge, or you can also call customer service from your mobile phone.
Once you have used up your data, your data speed will go down to 2G, and you will not be able to add any more data to your SIM. We recommend purchasing the Unlimited Data USA SIM card if you feel like you will need more.
