MTN.
I have used the Band Tools (with the help of @cavedog) to force to 900, 1800 and/or 2100. Just does not want to connect to the Cell ID I would like. This only happened within the last 2 - 3 days. As if it has disappeared.
That's why I was hoping if one could force Cell ID like what can be done with the bands.
Unfortunately not.
Do you see 4G+ in the router home page? Also cell ID can be different but that just means you are using another frequency.
MTN has their LTE-A network as follows.
Band 1 (10MHz down and 10MHz up) Refarmed 3G spectrum
Band 3 (10MHz down and 10MHz up)
Band 8 (5MHz down and 5MHz up) Refarmed 2G spectrum
In some cases especially in cities with high data volumes MTN has 15MHz down and up on Band 1.
For the best possible speed you would ideally like to aggregate these 3 bands. I'm not sure if there is a router that does it apart from the Huawei H113 5G CPE. I would recommend B1+B3 and then you can choose the upload that works the best for you be it B1 or B3. This is likely to give the best speeds as it has the most spectrum. As a last resort Band 8 can work when signal is bad as it's a low frequency band that travels further. Spectrum is low in this band so I doubt you will break any speed records but might be more stable.
