Hello 
I have an LG Optimus 2X Android mobile phone.  I have a Reliance SIM card.  
When I use the Reliance SIM card in my Micromax USB modem, the software displays an 'H' and the SIM works at 3G speeds. 
When I put the SIM cardin my Android phone with the network type set to automatic the display shows 'G', or 'E'. 
I am from England and my Hindi is very poor so whenever I call customer service there is no one who can help me in English. 
When I first got this SIM I was told there were more than one type of Reliance SIM and that you needed to use the correct APN.  I have tried both rcomnet and smartnet for the APN and still I only get 2G speeds on my phone. 
If I put my BSNL SIM in my phone with all the others settings still the same, the display shows an 'H'. 
Any ideas? 
best
