Supported Radio Frequencies (Bands) for Republic's New Data Only SIM


Republic has recently introduced a new cellular data only offering. The announcement is here: New from Republic Wireless: A data-only SIM card. A companion blog is here: Republic Wireless Unlimited Data-Only SIM.

Republic is testing the waters a bit, nonetheless, there have been some questions raised regarding compatible devices. Unlike Republic’s mobile phone service, there is no blended WiFi/cell service and no Republic app management of same to be concerned with. This is cellular data for Internet access. This new SIM does not provide Republic phone service and the compatibility requirements for that do not apply.

What is required for compatibility with Republic’s new data only SIM is a GSM unlocked device that supports the following:

4G LTE: Bands 2 (1900 MHz), 4 (1700/2100 MHz), 12 (700 MHz), 66 (1700/2100 MHz) 71 (600 MHz)

3G: Bands 2 (1900 MHz), 4 (1700/2100 MHz)

Generally, one will find support for Bands 66 and 71 on certain newer phones only. Data only devices (depending upon age) generally support Bands 2, 4 and sometimes 12.

The moral of the story, one will want to verify the specs of any data only device one is considering using with Republic’s data only SIM to be certain it will work as expected. One might also want to verify coverage here: Coverage Check | Republic Wireless.

So Roland, for “good” coverage your would recommend at least LTE Bands 2, 4 and 12 as these comprise the vast majority of the partner’s active coverage, correct? 66 & 71 would provide additional coverage (mostly rural) but will be hard to find on hotspot devices?


Generally, yes. Band 66 is essentially an extension of Band 4 (it operates on the same radio frequencies). Both Bands 12 and 71 are helpful in rural areas, however, one will be hard pressed to find hotspots or other data only devices supporting Band 71 (or 66 for that matter). Apple’s newest cellular enabled iPad Pros, for example, do support both Bands 66 and 71 but that’s exception rather than rule.

It’s estimated 80-85 percent of the U.S. population lives in an urban or suburban area. For those folks, Bands 2 and 4 might be sufficient but, bottom line, I would strongly suggest support for Bands 2, 4 and 12 for any device I was considering purchasing (as opposed to one already owned).


As there have been a number of questions regarding hotspots the SIM card would work well in. Here are some choices:



Thanks @louisdi, in time I’ll add those to the top post!
