When a user travels far and wide, it may not be possible for him to afford roaming charges for a long time. Therefore, the best way for him to be connected is to switch to a network which is local for that place. This would be against the network provider if the person is under a contract. It is rather better to go in for deals which are sim free and allow the users to switch to any other local network without any commitment or limitation. Pay as you go deal offers this freedom to the users with which they can easily switch networks according to needs.
Pay as you go deals are also beneficial in the case where a user is not getting adequate services and wishes to switch. Also, pay as you go deals are advantageous since they provide a control to the user of the expenditure that he makes on his phone. He can get his mobile account recharged according to his budget and then use it later on. Any latest handsets can be taken up for pay as you go deals.
Pay as you go deals make it really possible for the users to switch to better networks or save their money. No limitations can tie them down to one network.
