is there a beta firmware for the M7650? im having issues with the current firmware 1.1.10 like rebooting when using speedtest with smart sim (globe sim doesn't give me problems) and having low speeds

how do i enable 4g+ on my m7650? im using a smart sim card from the philippines but im getting low internet speed (not more than 1mbps) and its only showing 4g but when i use my globe sim its fine.

Is there a way to know which band my M7650 is connected and if the 3 carrier aggregation is working? I've been searching through the settings of my mifi but I can't find anything.
