Check whether 3G is enabled

Check whether 3G is enabled

Depending on your device, go to settings and find the network settings. In android devices, make sure the Enable 3G is activated by checking the box or set the Network mode to Auto if it was set to manual. If there is no ‘Enable 3G’ setting for older devices, it means your that 3G is enabled by default.

Is your device dual sim?

In most dual sim devices, 3G cannot be accessed by both sim cards at the same time. Open settings in your android device and search for Dual Sim 3G. Enable this setting by checking the box. If there is no such setting, it means that 3G is activated by default.

Check whether your sim is 3G enabled

Although quite rare these days, there are some network providers that haven’t made the shift to 3G from2Gtechnology. This means even if your phone is 3G enables, you will not be able to enjoy fast 3G speeds. Call your network provider and ask if your sim is 3G enabled. If it isn’t, consider switching to a provider with this service.

Check whether SIM is oxidized and/or dirty

A dirty or oxidized sim may cause connectivity issues. Remove the SIM card and check to see if the metallic surface has some brown deposits. The brownish material indicates that oxidation has taken place. Clean the SIM using a dry to dump microfiber towel and ensure it always stays clean. Additionally, if your SIM card is cut in a strange shape, reception may be affected. Use a normal shape SIM and test whether you get a 3G connection. If you do, consider replacing your SIM with a standard shape one.

Test the network connectivity in your area

It is quite common that the connectivity in your area is weak and may not support 3G connectivity. This is especially true when you’ve travelled to a new area. Check the connectivity of nearby devices with SIM card from the same provider. If the issue is persistent in the other devices, then it means the area is remote and may not be getting good network connectivity. When this happens, mobile devices automatically switch to 2G. If this is your problem, restart your mobile device, enable then disable flight mode and check whether the issue is fixed. If the problem persists, consider moving to a different area where network connectivity is strong.
