My Airtel 3G is showing H and H+ signals. But when it is showing H, it is not connecting most of the time. I thought it is a problem iwht my Samsung Galaxy S II but it is happening with my Lenovo A7000 as well. So, it is a problem with Airtel..
Basically this is a Network stability Problem has in UAE their are only two telecom provider's which are Old 'Etisalat' and new one 'DU' owned and controlled by local government only. Before I was using Sim of new telecom operator DU which always had this problems switching between H+ and 4G LTE with unstable connection then recently I switched to the older operator which is Etisalat and now i am always getting 4G LTE connection every where plus till this date never had any connection stability issue's. Its bcuz of your network's coverage problem which makes the connection unstable, just try sims of other networks which may have better coverage and network stability :k
4G+ Is Also Called As LTE +, 4G Ultra,4G Advanced etc...
In 4G+,The Telecom Combine Or Aggregate Multiple Spectrum Mhz Into One To Provide Higher Speeds.
