Best USA Carriers in America
Choosing the right carrier is essential for coverage and speed. The three major carriers are T-Mobile, AT&T, and Verizon.
T-Mobile is highly competitive, offering great prepaid options with excellent coverage across mainland USA and Hawaii.
AT&T has extensive reach across the USA and its territories. But with AT&T you will need to remember, new activation require you to have a AT&T approved 5G compatible phone, otherwise you will run into issues whilst over there.
Verizon - The last big mobile carrier is Verizon, which also provides excellent coverage and fast data plans. But this may not be an option for most travellers, as Verizon is only able to be used in conjunction with specific phones—mainly USA or CDMA phones, whereas those used in Australia are considered gsm devices. You don’t want to make the mistake of getting a Verizon SIM that doesn’t work in your Australian phone
There are also smaller carriers like LycaMobile and Lebara that use major networks. While these can be cheaper, coverage and speeds may be limited, and some restrict video quality. For the best experience, we recommend sticking with T-Mobile or AT&T for popular cities and tourist areas.
