There are various kinds of offers that are available over mobile phones like contract deals, pay as you go and SIM only. These deals are as per the requirement of an individual, like a business professional, who would like to keep a high end mobile phone for long, he would go for a contract deal for mobile phone, whereas a student or people staying in UK for short period of time might go for Pay as you go or SIM only deals.
Contract mobile deals come along with following the rules and regulation for a certain zong sim lagao offer code period of time. One cannot move before the contract period gets over otherwise the user is imposed with hefty penalty. The Pay as you go and SIM only deals are hassle free deals which gives user a freedom to switch to any provider any time.

The SIM offered in SIM only deal can work over any mobile phone unlike in pay as you go where phone gets locked if user tries to insert SIM of some other network. The handsets through Pay as you go are network specific and allow cards from the same network to be inserted or else get locked. The same situation can be faced by a user who might want to move to SIM only deal for some previously deal taken on some other network. In that case one may have to get it unlocked from the network provider.
