Smartphones, tablets and other devices make it easier for us to interact with our surroundings and have become our constant companions. They help us to quickly google the next restaurant or hotel, send photos to our loved ones at home, communicate with friends and the rest of the world on WhatsApp and Facebook or simply stay up to date.

To continue using your smartphone as usual and ensure easy, stress-free travel around the USA without roaming fees, it is recommended to use a Prepaid US SIM card.

H2O Wireless is one of the best providers in the USA. H2O Wireless uses the AT&T network, which offers extremely wide network coverage and excellent quality. So you will be well-connected with the largest network provider in the USA.

For normal browsers or power users, we offer generous data plans between 3 GB and 40 GB. The advantages of our US provider include generous free minutes to European landlines and mobile networks as well as a data flat rate. All rates include a flat rate for German, Austrian and Swiss landlines.

Use your mobile data as needed: when your data volume has been used, the speed will be restricted to 2G so you can continue to browse without limitations.

To make things as easy as possible for you, you can continue to use your account or local number for services such as WhatsApp, Skype, Facebook Messenger and more. You won’t have to change anything else on your device, so you can enjoy a stress-free holiday.

The US provider’s plans offer excellent value.
