If you're tired of poor service from your current telecom service provider but have not switched to avoid changing your number, you don't have to worry anymore. You can now leave your old service provider for a new one and keep the old number.
Procedure for MNP :
Send an SMS from your phone to 1900. Your present company will reply with a unique porting code. Use that code while filling out a detailed form for the company you want to shift to. Within 48 hours, that company will take over all your cell services. The fee charge may cost you about Rs 19.
Your cell number will be switched off for only one hour. All bills after that are paid to your new company. You'll be stuck with them for at least 50 days before you can shift again, so choose with care. While you can shift from a GSM service to CDMA or vice versa, you cannot shift from one state to another.
"The circles don't change. If you are in Karnataka, you are a Karnataka subscriber. If you shift from one state to another, roaming kicks in, just like it does right now,"
While keeping in mind MNP, companies are coming out with best possible plans to attract customers. BSNL gonna offer free sim card + Rs. 100 Talktime + GPRS free depending upon scheme of indvidual.
Vodafone is planning to give 100 mins free to vodafone to vodafone calling.
HAVE FUN !!! :-)
