IP Phone
An IP Telephone is a phone considered to work with an IP PBX but the IP PBX as we know it today has evolved, almost generally, into a SIP-based PBX. IP phones connect to your phone service via the internet, using an Ethernet cable or WiFi connection. IP phones include desk phones, cordless phones, and conference phones that resemble your everyday office phone, but use a different technology for powering calls since it transmits voice data digitally.
Another great quality of these types of phones is that you can use them in any location where you have internet connection since it does not rely on the physical location of the office. Thus, you can unplug an IP phone, take it to another location, and plug it in again where your line and its settings will be unchanged. GTI tests its software with all major brands to ensure compatibility.

What Is a SIM Card?

A SIM card lives inside your cell phone and is essentially your phone's ID. It stores contacts and other data, and your phone won't work without it. A SIM card works by connecting with your mobile phone and your carrier's cell towers, so the two can communicate. When you upgrade your phone, you bring your SIM card with you to keep your phone number, data plans and more; but since most SIM cards are designed to work only with certain brands and carriers, they won't fit just any phone.

 What Are the Types of SIM Cards?
 
GTI Global SIM Cards usually come in one of three popular sizes: Regular SIM cards, micro SIM cards and nano SIM cards. A nano SIM card offers the same features as larger cards do, but in a more compact package. Many phones are equipped with cutouts for all three sizes, so you can decide which version you want. If your phone only fits one type of SIM card, you can try using an adapter, which allows nano SIM cards to fit into micro SIM or regular SIM slots.
