When choosing between WCDMA and GSM, it depends on your specific needs and location. WCDMA offers faster data speeds and better call quality compared to GSM. However, GSM is more widely supported globally and is compatible with more devices. If you prioritize data speed and call quality, WCDMA may be the better choice, but if global compatibility is important to you, then GSM would be the preferred option. **

As of 2021, many countries still maintain GSM 2G mobile networks, including the United States, Canada, Australia, and various countries in Europe, Asia, and Africa.

Additionally, 2G networks are often used for machine-to-machine communication and Internet of Things (IoT) devices. **

Yes, 170 gsm paper is thick enough for watercolor paints.
