Maybe you already know: using 5G as fixed Internet, without worrying about running out of capacity or incurring charges

Until now, I thought 5G was only for use on phones. It turns out that there is now a fixed Internet solution using 5G, quite suitable for backup needs or places where it is difficult to pull cables. Only now do I know that MobiFone has FWA (Fixed Wireless Access) service, which simply means fixed Internet running on the 5G network. What I find good is that this package has no capacity limit, so you don't have to worry about being charged extra or running out of data if you use it too much like regular 5G packages. For businesses, this can be a quite reasonable backup transmission option. If the main connection has problems, there is still Internet to maintain work. A small tip before investing is to get a 5G MobiFone SIM, stand in the exact location where you intend to place the device and then run Speedtest. If the speed and signal quality are good, you can almost imagine the actual experience after installing FWA. This is important because if you prioritize the upload path low, it will not meet the requirements. Of course, FWA still has some limitations. For example, it is not possible to open ports (port forwarding) like many fiber optic lines, so it will not be suitable if you need to directly access the NAS, camera or server from the outside without using VPN or intermediary solutions. In my opinion, FWA is not really meant to replace fiber optic cable, but is more suitable for places that need to deploy quickly, have difficulty pulling wires, or simply want to have an additional backup transmission line without having to worry about exceeding capacity or incurring charges. In case you take your SIM somewhere else to use, it will likely be locked or limited in data traffic according to the service commitment. Source
