Flag of Guam

Basics[]

Guam and the Northern Mariana Islands are territories of the United States that are not part of the 50 core states. They share some things with the mainland like the country code +1 and their currency is US$. But they also have some significant differences with the mainland, such as having additional visa waiver countries, and more importantly their own independent cellphone networks.

Flag of the Northern Mariana Islands

The Commonwealth of the Northern Mariana Islands (in short CNMI) is connected to Guam and mostly the same cellular networks operate here. Major US network operators such as AT&T or T-Mobile have no operations here, and consider these islands to be "international" with high roaming charges, or no roaming at all.

Instead, there are 3 LTE operators available on prepaid:

  • DoCoMo Pacific (owned by NTT DoCoMo in Japan)
  • GTA Teleguam
  • IT&E / iConnect ( Merged)

Cellular coverage is on US-American frequencies: 2G on 1900 MHz, 3G on 850 MHz and 1900 MHz and 4G/LTE has started on 700 MHz (B12/17) and 1700 MHz (B4). CDMA and GSM systems still co-exist like in the US.

DoCoMo Pacific[]

DoCoMo Pacific (formerly called Guam Wireless) offers 2G service on 1900 MHz, 3G/UTMS on 850 MHz, and 4G/LTE on 700 MHz (B17). Coverage is on Guam, Saipan, Rota, and Tinian: Coverage map.
