How to upgrade 4G to 5G network

No, you’ll need a new phone as older phones can’t be updated to support 5G because they require a 5G chipset and modem . If you have a 3G or 4G phone it will still work on 5G plans, but you’ll only get 3G or 4G speeds.

So yes a 5G network will require a SIM Upgrade although all the SIM Cards are backward compatible with previous generation.

Answer: Yes. If you’re among the 86 percent of the population who are concerned that the recent rollouts of 5G networks will make your 4G cellphone obsolete, there’s no need to worry. 4G phones still work on a 5G network, they just won’t get that coveted 5G speed.
