How to turn on 3G network on mobile phone

With the popularization of 5G networks, 3G networks are gradually being marginalized. However, in some specific scenarios (such as insufficient signal coverage or device limitations), users may still need to switch to 3G networks. This article will introduce in detail how to turn on the 3G network on your mobile phone, and attach recent hot topics for reference.

2. Steps to enable 3G network on mobile phone

Different brands and operating systems have slightly different settings for mobile phones. The following are operation guides for common models:

Mobile phone brandOperation pathThings to note
iPhoneSettings > Cellular > Cellular Data Options > Voice & Data > Select 3GRequires operator support
HuaweiSettings > Mobile networks > Mobile data > Preferred network type > 3GSome models have no options
XiaomiSettings > SIM card & mobile networks > Preferred network type > 3G onlyNeed to turn off the 5G switch
OPPOSettings >SIM card and traffic management >Preferred network type >3GRequires restart to take effect

3. Why do you need to switch to 3G network?

1.signal coverage problem: In remote areas or buildings, when the 5G/4G signal is weak, the 3G network may be more stable.

2.Power saving needs: 3G network power consumption is lower than 4G/5G, which can extend the battery life of mobile phones.

3.Compatible with older devices: Some elderly phones or IoT devices only support 3G networks.

4. Precautions

1. Operators may have closed 3G base stations in some areas, so you need to confirm local network coverage in advance.

2. The 3G network speed is slow (theoretical peak value is about 42Mbps) and is not suitable for high-traffic scenarios such as high-definition video.

3. When roaming internationally, some countries have completely withdrawn from the 3G network, so you need to check the destination network policy.

5. Technology comparison: 3G/4G/5G

Network typeTheoretical speeddelayTypical applications
3G2-42Mbps100-300msVoice calls, basic Internet access
4G100-1000Mbps30-50msHD video, mobile payment
5G1-10Gbps1-10ms8K live broadcast, autonomous driving

As global operators accelerate the withdrawal of 3G networks (for example, China Unicom plans to completely shut down 3G in 2024), users are recommended to upgrade to equipment that supports 4G/5G as soon as possible. If you must use the 3G network, it is recommended to contact the operator to confirm the specific network withdrawal timetable.
