This is very annoying and you will always need to Force 4G network. Let us know now how to keep your phone permanently on 4G network only without missing phone calls.
When in areas with poor 4G coverage, your phone will automatically switch to a 3G network that is less than 4G or to a 2G EDGE network. Due to this you cannot get 4G continuously. In such cases, your phone must be locked to the 4G network. But if this is not done correctly, there may be problems in making phone calls.
