Your phone can support 5G and still not work on Zimbabwe’s 5G networks.
The reason is that 5G is not one single frequency. Mobile networks use different frequency bands, and phones are built to support specific ones.
In Zimbabwe, Econet’s 5G uses the n78 band, which operates between 3.4 and 3.6 GHz. The band has been cleared for 5G use by POTRAZ.
This is where imported phones can cause problems.
A phone bought in the US, Japan or another market can have 5G on the box and still not support n78. It might work perfectly well on 5G in the country it was made for, but with a Zimbabwean SIM, it could fall back to 4G because it cannot connect to the band Econet is using.
So how do you check?
Start with the phone’s model number. You can usually find it under Settings > About phone. It will look something like SM-G782B.
This matters because the same phone can have several regional versions. A Samsung Galaxy sold in Europe, for example, can have different network support from the version sold in the US.
Once you have the model number, check the manufacturer’s website. Search for that exact model number and open its specifications page. Look under the network or connectivity section for the supported 5G bands.
You are looking for n78 or just 78.
If the manufacturer’s website does not give you enough detail, GSMArena is another useful option. Search for the phone, find your exact model number under its different versions, and check the 5G bands listed for that version.
The exact model number is important. Do not just search for "Galaxy S24 5G" or "iPhone 16 5G" and assume every version supports the same bands.
This is why buying an imported phone can sometimes be a gamble. Two phones can have the same name and both advertise 5G, but their network hardware can support different bands.
So if your phone refuses to connect to Econet’s 5G, it does not necessarily mean the phone is faulty or that there is something wrong with your SIM. Check the model number first, then see more....
