Aircel 3G problems. Help

I have a Samsung Galaxy SII 19100 phone.1. I recently got a 975 unlimited 3G data plan from aircel. 2. Before that I was using the default plan which came when I activated 3G by an sms (START 3G). 3. All along my Internet connectivity was great with good speeds. 4. After the change of plan however I am not getting full connectivity. 5. I was sent pocket internet settings which I saved to my phone. 6. While browsers work fine with the new setting, my other apps like Youtube, market, maps, updates etc do not work and shows a "network connection not available" message.Android market keeps loading forever.7. I tried all sorts of settings like changing the APN (aircelwap, aircelgprs, aircelgprs.po, aircelweb, etc) but it still does not work.8. I can however access everything through wi-fi so I know its not a problem with my device. 9. Aircel customer care has not been a big help either.I request anyone with any ideas otherwise I plan to change either the set or my service provider.

problems lies when you had done plan change, as said in my earlier post. when you had done plan change, software at service provider side some time generate error log while switching to new plan. implications are as follows:1. 3G will get activated but will not be factored as per rate plan and result : Huge bills and no libility from operator as they dont simply eaccept mistake.2. speed will not be set as per tariff plan. technical team always sleeps on it, problem they dont have enough bandwidth to look into so many error reports. ------this is your problem

Wow. Thanks which if true means I'm in big trouble.
