What is the difference between those two? I have recently activated 3G on my phone .. But it shows "H" symbol and 3G is never shown on the screen. Why is that so?Although I get 2Mbps speed but still why my phone won't show 3G on the connection symbol? I have Optmius one p500 ..Second query is for Vodafone user... I have posted in other thread too but never got a reply I have subscribed to both VMC and 3G pack.. So if I deactivate VMC and just subscribe to 3G 100MB pack .. Will it work?Will I be able to connect to laptop? Currently I can connect to laptop .. by making the phone as hotspot ..I just wanna make sure tht even if I unsubscribe from VMC... would I be able to connect to laptop like I do now?Also for now data usage while roaming is free for me under VMC plan .. Will it be same under 3G plan too?
