Lumia 820 3G connectivity issues

[Anonymous]

I am having difficulties with connecting to the Internet on 3G. My phone shows the H symbol. Before it used to show H+. Since not long ago, the highest connection type is H. I cannot connect to the Internet or carry out any activity which requires Internet access. 

Please help.

4g is the only cure I've found so far mate.

Yes I am gonna look into 4G tariffs. Recommend any good ones?

EE or Three depending on your location

I thank you kind sir. Your recommendations have been duly noted.

To be fair to o2, their 4g is very good, when you can find it. EE and Three have better coverage though.

I mainly go back and forth between London and the midlands every now and again so coverage won't be much of an issue. But I find o2 is a much better network. That's just my opinion

Test some PAYG sims from other networks and see what works best for you.
