Do you understand what this works only with 2G, 3G networks? A proper 4G is data-only one, so the SMS there are emulated over a data link.
- pjmlp 3y agoPlenty of those around Europe still.
- kiwijamo 3y agoSMS generally will deliver quicker and with more reliability in low reception scenarios. I've been in places with 1 bar of reception where data barely works so the likes of WhatsApp/Messenger/Signal/etc is hit and miss, whereas SMS just works. On Apple devices iMessage has a fall back availiable to pure SMS. This is less of an issue with modern LTE networks (which performs much better with low signal) but this was quite common in the GSM and UMTS days. Depending on where you go there may still be legacy UMTS/GSM only coverage.
