Currently, 5G networks may be unavailable in some areas. We recommend that you contact your network operator to confirm network availability and whether your SIM card supports a 5G network.
If both the local network and the SIM card support a 5G network, try the following to fix the issue:
1. Go to Settings > Network & internet > SIMs Card > Data Preferences to check if you have selected the correct option.
a) Tap the corresponding SIM and check whether the mobile data switch is turned on.
b) Tap the corresponding SIM and check whether the preferred network type is set to 5G.
c) Check with your network operator if there are roaming restrictions. If so, select the corresponding SIM and check whether the roaming switch is turned on.
d) Select the corresponding network card, and check whether the data warning and limit exceed the limit.
2. Go to Settings > Battery and check whether the battery power saving mode is turned on. Turn it off and check again.
3. Switch airplane mode on or off or restart your phone and check again.
If the issue persists, contact our Customer Support for further assistance.
