What is the difference between GSM and UMTS?

GSM is an abbreviation of a global system for mobile communication; it was originally known as special group mobile. The global system for mobile communication can be referred to as a service or technology. GSM is the second generation (2G) telecommunication that was introduced in the 90s.

it uses a variation of time division multiple system access.it is still widely used for mobile service; there are about 700 mobile networks that provide GSM service in various countries. UMTS is the third generation (3G) of mobile telecommunication technology; it is used for smartphones and PDAs today. UMTS has a faster data transfer rate than GSM with 3.6 Mbits per second. UMTS is mainly based on CDMA (code division multiple access).

GSM or Global System for Mobile Communication and UMTS are two types of telecommunication technologies that offer mobile services for mobile phones, smartphones, etc. There are some differences between the two. GSM is the older of the two, and it is usually referred to as a second-generation telecommunication technology. GSM was introduced in the 90s.

However, its system has been upgraded in order to give a faster speed, which is usually about 144kb/s. On the other hand, UMTS belongs to the list of the third generation mobile telecommunication technologies. The fact that the 3G mobile network offers more speed than 2G shows that UMTS allows data transfer at a faster rate than GSM. And the implication is that you get to enjoy faster internet connection when you use UMTS than when you use GSM. UMTS makes use of Code Division Multiple Access, whereas GMS uses Time Division Multiple Access schemes.
