I pressed ALT and 311 (holding alt)
It warns that if you do this it may never reconnect to Amazon's Whispernet.
It doesn't find any providers for ages and then lists three:
Vodaphone (2G)
Eir Mobile (2G) (default)
O2 IRL (2G) (which is long gone, bought by Three).
I pressed Home rather than change anything. Only Auto will work and only where the operators have roaming agreements.
Those would be EDGE which is 245 kbps. Original 2G was 14.4 kps and 3G was 348 kbps. The higher speeds were later protocols piggybacking on 3G channels.
The 2G (likely mix of 14.4 kbps for phone alarms and EDGE) is still used for smart meters, traffic lights and alarms in Ireland and UK and likely other places. The European 2G is unrelated to USA 2G (GSM vs CDMA). Much 3G was replaced by 4G using the same channels. The GSM uses smaller channels.
It's years since I saw my DXG show 3G. It puts a small
EDGE beside the signal bars, when you press menu.
All European & UK 3G modems do GSM/2G EDGE and basic GSM. Most do HSPA and related faster 3G. All 4G ones also do HSPA, basic 3G, GSM/2G EDGE and basic GSM.
The 5G is pointless as it's short range and drops out. It's for paid hotspots, race courses and stadiums etc.
I have a 3G phone used till lately, but data only on WiFi. The voice and SMS is actually more reliable on GSM version of 2G as there is no Cell breathing (causing disconnections) as on 3G and the defunct USA 2G = CDMA.
