Is there a downside to disabling 2G?

[–] [email protected] 4 points 1 year ago (4 children)

I would say there is. Many providers are disabling 3G nowadays and 5G is not available for all yet, so your phone essentially uses 2G and 4G. Now, imagine disabling 2G and calling someone on a moving vehicle...

No major U.S. carrier gas used 2G for years. Well, at least Verizon and AT&T. Sprint did as well before merging with T-Mobile. That are shutting down 2G this year. So, not really a big deal.
