Here in the USA the 3 major networks (AT&T, Verizon, and T-Mobile) are phasing out the 3G phone signal.
I found out this week by losing the ability to call or receive calls, that my phone is 3G even though I have read it's 4G LTE. --Samsung Galaxy S7
I am debating on going back to a non-smartphone. Talk, Text, and Camera only
My last 2 phones were also IP68 rated for durability because of the sometimes-harsh environments I have found myself in. (S7 and Casio Boulder)
What types of phones do you use? Have you gone non-smartphone? Do you consider the IP68 rating? How do you like what you have?

Apparently your phone is 4G capable. I would check with your network purveyor and see if your "account" is restricted/throttled to 3G. Perhaps an network access upgrade is all you need. It is a favourite past time of networks in Canada to find ways to up-charge for any little change in access.
