You can consult your local operator to check the 5G signal coverage.
5G turn on method:
realme UI 3.0 & above versions: Settings > Mobile network > Click the corresponding SIM card > Turn on 5G.
realme UI 2.0: Settings > SIM card & mobile data > Click the corresponding SIM card > Turn on 5G.
There are several ways to check 5G signal coverage in your area:
Use a network coverage map: Most mobile carriers provide coverage maps on their websites that show where their 5G networks are available. These maps can be a good starting point, but they may not be entirely accurate, as they don't always reflect real-time network conditions.
Check your phone: If you have a 5G-capable phone, you can check the signal strength by looking at the signal bars in the status bar. If you have 5G signal, the signal bars will be green or blue, and you will see a "5G" icon next to them.
Contact your mobile carrier: You can also contact your mobile carrier to ask about 5G signal coverage in your area. They should be able to provide you with more specific information about where 5G is available and what speeds you can expect.
Once you have checked 5G signal coverage in your area, you can decide whether or not to upgrade to a 5G device and data plan. If you live in an area with good 5G coverage, you may be able to take advantage of faster speeds and lower latency. However, if you live in an area with limited 5G coverage, you may not want to upgrade just yet.
