The Nokia N95 hit the market in 2007.
Registering a Subscriber Identity Module card is necessary when you activate the Nokia N95 on a wireless service provider's network. Understanding a few aspects of SIM card technology helps you troubleshoot when you are unable to register the phone's SIM card. Most of these conditions are easily dealt with, though some require you to exercise a little patience.
SIM Technology
A SIM card stores data that is relevant to both you and your Nokia N95, including the device's phone number and your account information. The phone's wireless service provider requires this information to activate the phone and give the phone access to the network. The SIM card is made of a sensitive microchip that is easily damaged, especially if it has been transferred between devices on multiple occasions. A damaged SIM card can fail to connect to the N95's processor, making it impossible to register the card with the phone's carrier. In this case, replacing the SIM card with one that is undamaged typically resolves the registration problem.
Networking Problems
The Nokia N95 is a Global System for Mobile Communication phone -- commonly referred to as a GSM phone -- that is only compatible with networks that use GSM technology. At the time of publication, AT&T and T-Mobile are the only national carriers that operate GSM networks. Cell towers play an integral role in registering and activating the phone and its SIM card for use on a GSM network. Extreme conditions, such as stormy weather and high volumes of traffic, affect a cell tower's ability to handle cellular transmissions, such as registering a SIM card. Extreme conditions like these are outside your control. Wait until the weather settles and try the process again to see if your SIM card registers.
Compatibility
SIM cards are interchangeable between GSM phones. However, the cards may be outdated and incompatible with newer mobile phones. For instance, if the SIM card in your Nokia N95 was originally contained in a phone that was several years older than the N95, your SIM card and phone may not be compatible with one another. In this case, you will not be able to register the card and use the phone on your provider's network. Obtain a new SIM card is simple to do, which is relatively inexpensive, to eliminate the registration problems.
Carriers
The N95 will not work on Code Division Multiple Access networks, such as the ones offered by Verizon Wireless and Sprint. If you are trying to switch your service from T-Mobile or AT&T to Verizon or Sprint, you need to purchase a CDMA phone from your new carrier.
