Since upgrading from s9+ I havent been able to get any Internet whilst indoors, unless its my WiFi, and only H+ and very rarely 3g when I'm out and about. There is no option for 4g on this phone, and my data is 120gb a month. So, does it mean I cant get 4g on this phone when 5g isn't available? Or that 5g is available in my area, (it is according to the checker) but my included data only covers 4g, on a phone that doesn't have 4g? If the latter is the case, then I have been sold an airtime plan and phone that are not compatible? I have tried many things to try and sort this, but thats all I can come up with thats left. Please help. Thanks in advance.
