The International Comrex Connect is designed to work in many countries. It is unlocked and carries
PTCRB certification, so it should be allowed to register on most networks worldwide. While it covers
most of the bands used by carriers in the U.S., it does not carry the carrier-specific certification required
to be used on these networks.
LTE coverage by country/region:
In Europe and Africa, Bands 20, 7, and 3 are most common and are covered by the modem.
This modem also supports Band 8, used by a select number of carriers in Europe.
In most of Asia, Bands 7, 3, and 1 are common, exclusive of China, Japan, and India.
Most Chinese carriers use TDD, so support is limited to carriers that operate on Band 41
In Japan, support is limited to carriers operating on bands 8, 1, and 3
In India, some carriers use band 41 (TDD) and others use Band 3
In Oceania and the Middle East, Bands 7 and 3 are common.
In Canada, Latin America and the Caribbean, Bands 7 and 4 are common

Since the Comrex Connect modem is certified to work on most networks, you can deliver the IMEI
number of the modem (from the label) to the carrier. The carrier will provide a SIM card for your
modem. Request a “full size” SIM card if possible.
It’s also often possible to move a SIM card from an existing USB modem or Hotspot (or even a tablet) and
use that data service directly on the Comrex Connect.
