Why my phone can't use 4G
how to do my phone to get 4G
Hi,
Has it worked OK on 4G before?
If not check if your SIM card is 4G compatible . If your SIM card is not 4G compatible, contact your service provider about getting a replacement SIM card.
If your SIM card is 4G compatible have you checked that the Network mode setting is set to LTE (or 4G) (go to Settings > Networks > More > Mobile Networks > Network Mode) and have you enabled Mobile data (go to Settings > Networks > More > Mobile networks > Mobile data)?
