So, the difference is only one band. Also, if I understand correctly, SMS could still go via 3G or 2G, either in parallel, or by restricting to 3G.
Rogers is the only Canadian carrier that has a 2G network since they were GSM based from the beginning. All other Canadian carriers were CDMA, transitioned to HSPA+ AND did not requiring their new “4G” phones to have a CDMA fallback, unlike Verizon. They went from CDMA right to LTE thus needing CDMA for voice calls until they got VoLTE.
@Richard, I didn’t notice that variant before, as it is only mentioned in the data sheet, not the website. Maybe this variant was added after the decision was made?
That I couldn’t say but I don’t know of any major GSM based carriers use that band. Freedom Moble (previously Wind) does not use Band 13, they use Band 66 for LTE and if I remember correctly they’re the first carrier in the world to use it. It’s also listed as AWS-3.
SMS should be going (end-to-end encrypted) via the internet, where there is some hope of privacy and security.
Unfortunately that’s not how SMS works. Unless they’ve got VoLTE, SMS goes through carriers Voice cores and not their Data Core. To encrypt SMS both parties generally need a special app and at that point you might as well just use… Librem Chat!
Haha as smooth as an LTT sponsorship segue.
