Majority of US cell carriers are discontinuing 3G support. Verizon, AT&T, T-Mobile, etc are all stopping 3G coverage within the next month or two. What is the solution going forward?
Reach RS2 internal modem automatically switches to 2G if there is no 3G.
I know 2G is slower. But it’s not an issue for RTK because RTCM3 messages with corrections are lightweight. So 2G is more than enough for stable performance.
In some parts of Europe, 2G has been switched off for a long time.
Maybe 3G will stay a little longer.
But the question remains. What if no 2G and *G is available anymore?
@svetlana.nikolenko almost all carriers in the United States have already stopped their 2G networks (except for T-Mobile which will do so in 2022) so there is no 2G fallback in the US. Will this mean that the RS2s will not function at all with SIM cards?
Most of America’s largest carriers have already shuttered their 2G service or plan to soon:
- AT&T stopped servicing its 2G network back in 2017.
- Verizon Wireless phased out its 2G CDMA network at the end of 2020.
- Sprint sunsetted their 2G CDMA network in December of 2021.
- T-Mobile plans to sunset their 2G network in December of 2022.

In that case, Reach will work with Wi-Fi only as it depends on the hardware. We usually try to provide you with an alternative solution. If there will be one, we’ll let you know.
That means I get the RTK via the cell phone and connect the RS2 to the cell phone via WiFi?
In Switzerland it was announced that 3G would be switched off at the end of 2024.
Yes, you’re right.
