US Prepaid Plans:

Network coverage in the USA

Depending on where you are traveling in the USA, it is important to select the right network in advance. In general, AT&T provides the largest network in the USA and therefore also provides the best network coverage.
With the AT&T network, you will have ideal coverage in large cities such as New York, Hawaii, Las Vegas, Miami, Los Angeles or on road trips in campers or cars across the States. Reception is only very hard to find in Page and around the Grand Canyon.

Plans and providers

Just like in your home country, the selection of plans is very large. As a rule, anyone who wants to use tethering should choose AT&T and anyone who needs to make lots of calls to landlines back home should opt for H2O instead. Otherwise, the only differences are in choosing the amount of data.

Network coverage AT&T USA


AT&T is one of the absolute top providers in the USA. They guarantee the best network coverage. In addition to a fantastic network they also offer a wide range of provider stores where you can request technical support at any time. Employees will help you to configure your device or (in some cases) can exchange a SIM card free of charge in case it is defective. In contrast to many other providers, AT&T offers a first-class user experience. This especially includes the technology used for transmitting data, and of course HD voice technology.

T-Mobile Coverage USA


In the USA, T-Mobile is one of the more recent providers. Meanwhile, it has worked its way up to the third largest mobile provider. In the States, the originally German company is known for its extremely fast network and also delivers a very good network coverage - even in more remote areas such as Arizona. With all of the plans we offer, crossing borders to Canada or Mexico is no problem at all as roaming is already included. Similarly to AT&T, you’ll have access to Tethering throughout your entire trip. This way, you can use your smartphone as a Hotspot and share internet connection for up to 10 devices.

Network coverage H2O Wireless USA

H2O Wireless

H2O Wireless is a third-party provider from the USA that uses AT&T’s ideal network coverage. H2O Wireless particularly focuses on international communication. Every plan automatically includes a landline flat rate for calls to Germany, Austria, Switzerland, Belgium, Netherlands, Italy and many other European countries.

Difference between H2O and AT&T

H2O is a third-party provider in the USA, similar to Congstar or ALDI Talk for us. This has benefits particularly in terms of price, since H2O does not have independent stores in the USA, in contrast to AT&T. This allows H2O to offer cheap alternative plans that include benefits relating to phone calls to Europe in contrast to AT&T’s plans.
On the other hand, AT&T offers some services that H2O is unable to provide. This includes the option of using tethering (hotspot). For phone calls, AT&T uses HD voice technology to guarantee clear voice quality.

Provider Flat rate USA Flat rate German landlines Free minutes German mobile network Mobile internet Tethering Order
H2O Wireless yes yes 100 to 333 min. 2 to 30 GB data flat rate no H2O Wireless
AT&T yes 250 / 1000 min. (optional) no 5 to 22 GB data flat rate yes AT&T
