Technical Requirements:

You need a tri- or quad band device (GSM 1900 / GSM 850) without SIM-lock. For UMTS, use a device with UMTS 1900 / UMTS 850 function. This is the case for most phones from Germany/Europe. Please check whether your phone meets the demands before you order. The frequencies for LTE are 700 / 1900 / 2100 / 2300 MHz. Otherwise, the usage of HSPA+ is possible. Depending on your device you can reach the highest limit of LTE - speed. Attention: Often problems occurred with dual-SIM-cell phones. The SIM either has not been recognized or worked erroneous. We advise against using dual-SIM-phones with American SIM cards to avoid stress and unnecessary charges.

In case you would like to use a smartphone by Huawei, please ensure, that your device covers the respective frequencies.

The following options for Canada are available

All options can be also used in the USA (AT&T) and Mexico (Telcel). Further components of all options are a US-Allnet-Flat, an SMS flat to 100 countries (D, A & CH) and a flat rate for calls to Canada and Mexico. This flat can also be used in Canada or Mexico for national calls within these countries, as for calls to Canada and Mexico, or the United States.

Please consider: AT&T can reduce data speed temporary due to network overload. Then, video streaming is reduced to 1.5 MB/s in standard definition quality (appr. 480p). Check att.com/broadbandinfo for details about the standard guidelines on AT&T-network management. Mobile hotspot usage is prohibited.

travSIM has no influence on the network quality and can therefore not guarantee for it.
