Q.8 What is RUIM.
Ans. It is a CDMA SIM, just like SIM in GSM network. The full form is Removable User Identity Module / Re-Usable Identification Module.

Switching over from one phone model to another has never been easier. Now the process has become quite simple with the advent of Re-Usable Identification Module, also called RUIM card (R-UIM). An RUIM card is a removable ID chip for cellular phones made for the Code Division Multiple Access (CDMA) network. It stores the user's personal information such as name and account number, cell phone number, phone book, text messages and other settings.

To switch over to another phone, all that you need to do is remove the RUIM card and slip it into another card-enabled phone. What's more, you will be able to make and receive calls on the new phone under the same account without having to go through the carrier for activation. For instance, you can have several phones and switch between them or borrow a phone from your friend to make a call with your own RUIM card. You can even switch to another carrier and keep your old phone - the new carrier would simply issue a new RUIM card to use in your existing phone. You should only ensure that the phone is unlocked and compatible with the frequency band of the new carrier.

The idea of an RUIM card might be new to those who have had cellular service with a CDMA carrier. But this concept has been in vogue for some time now in the technology called Global System for Mobile Communication (GSM), which is popular in Europe and most countries outside of North America. This technology has a much larger overall share in the world market. GSM phones use a card similar to RUIM card, called Subscriber Identity Module or 'SIM' card. The SIM cards and RUIM cards will be interchangeable in phones, thereby allowing the consumer maximum flexibility.

An RUIM card would make CDMA more attractive to consumers and also open the door to better roaming between CDMA and GSM networks, thereby allowing the best possible global coverage for all cellular customers.

Ans For accessing EVDO services - EVDO data card is used. For accessing 1X data service, either NIC card or IFWT/FWT having internet facility is used.
