The iPhone 4 is compatible with the micro SIM card only and therefore you lose of the other options that are available with the latest designs of the SIM card. This is where the Nokia 603 smart phones excel and they are really good.
As far as the compatibility of the phone goes one can be said firmly and that is the iPhone 4 only supports the micro SIM card option and they are definitely not compatible with the different other types of the SIM card. The thing that this can mean is that you get to miss on the lot of things that the other types of the SIM card has to offer for you. Take into account the fact that you would like to use the dual SIM cards or may be some other option then surely this is not the device that is meant for it. It is a kind of customized thing. Now talking about its comparison with the Nokia 603 smart phones it can be seen that there is a lot of difference. The Nokia 603 is more improved one as compared to the Apple iPhone 4. This is considerably very useful as you will get to enjoy the benefits of all the functions that the micro ones provide as well as the functions of the other ones. This is particularly quite helpful as you have a lot of options to use around. This is one thing where it can be said that the Nokia 603 beats the Apple iPhone 4 hands down and it is really tough for the Apple one to get to the Nokia ones seeing the rigidity that it has.
Another important thing that is to be noted as far as the use of SIM card goes is that different mobile companies have different plans for the SIM card and therefore there are promotional coupons and codes that are also associated with the calling rates and the overall things. You are surely going to lose on all the things if you are the one who is using the iPhone 4. All this things are made for making the life simpler and therefore such kind of rigidness can really affect the things. You must be fully aware of the kinds of things that you device is fir for and therefore one can easily say that as afar as the offers as associated with the different companies and the kind of range they have the iPhone 4 is certainly not the thing that is designed for that. However the Nokia 603 is every bit the class act that you have been looking for and you out in everything and it will be fit for that. Here one thing also needs to be added and that is you can not switch over the SIM card to some other smart phone in case of iPhone 4 but you can definitely do that with the 603 one. This is the feather in the cap for the Nokia smart phones.
