An unlocked tri-band cell phone watch is no different in its general use than an unlocked tri-band cell phone. By determining that the watch's frequencies will work with your carrier of choice, and then obtaining that network's required SIM card, you will be able to use all the features found on your cell phone watch.
Instructions
1. Determine what three cell phone frequencies your watch uses. Available worldwide GSM frequencies include 850mhz, 900mhz, 1800mhz and 1900mhz. You can find this information in your phone's manual, through the manufacturer's website or through popular phone specification services such as GSMArena and Phonescoop.
2. Find out if your carrier of choice supports any of the frequencies of the watch. Quick tip: AT&T Wireless supports the 850Mhz frequency and T-Mobile supports the 1900Mhz frequency. You can also call the GSM carrier in your area and ask them if they support any of the watch's frequencies.
3. Call your carrier or visit a local retail location and sign up for an account if you don't already have an active account. If you don't have an account, you will be given a new SIM card. If you do have an account, you will be able to remove the SIM card from your phone and use it with the watch phone. For new customers, explain that you already have a phone with the proper frequency capabilities to work on the company's network.
4. Locate the watch's SIM card slot. Typically, this will be found on the side of the watch or under the watch in a removable area. Refer to the watch phone's manual or the manufacturer's website to find the SIM card location.
5. Insert your SIM card and power on the device. Attempt to make a call and then arrange to receive a call. If calls can be made and received, the phone is ready for service.
