6 Best SIM Cards for USA When Travelling from Other Countries

Using the best SIM cards for USA when you’re from another country can really make a difference in your budget. Roaming charges are quite expensive. The better and cheaper way is to use a prepaid SIM card during the duration of your stay in the country.

International Roaming vs Best SIM Cards for USA

When you travel to the US and want to use your phone there, you have 2 options: international roaming (using your current SIM card) or purchasing a new US-based SIM card.

If you just go to the USA for a day or 2, then you can just use your SIM through international roaming. Your network will charge you per usage (calling, receiving calls, texting, using mobile data).  However, international roaming can be expensive especially if you frequently use your phone for texting, calling or accessing the web. Plus, you’ll have to set up your phone for international roaming before travelling.

If you stay in the USA for a few days, weeks or months, then the cheaper option is to buy a new SIM card. Just make sure that your phone is unlocked in order for you to insert and use a new SIM card on your device. Typically, you’ll get 3G coverage on your phone in most SIM cards. However, for 4G LTE coverage, it depends on your phone model or the carrier you’ll choose.

Using the best SIM cards for USA can really save you money. So it’s important to only choose the right network for your phone and the right SIM card for best value. If you’re from the US travelling abroad, then these phone plans for international travel will save you bucks. When travelling, these Android travel apps will also come handy.
