Can I port a number in if i'm under contract?

Yes you can! However, the device that is under contract or lease will NOT be able to be used/activated. You will need to have an unlocked device to port to. Why? Your device is under a financial obligation with another carrier or phone lessor. If the financial obligations have not been met then that carrier or company will not release your device for activation elsewhere. The phone number however is not under any obligations and therefore only the number can be switched over to Tesix Wireless.

Danger Will Robinson! Your service MUST remain active with your current carrier in order for them to release your number. Why? If your number is not activate on your previous carrier, unfortunately your previous carrier will have nothing to approve; the number will be inactive. Conclusion Keep your current service active until you port to Tesix. Your old carrier will automatically cancel the services once you port your number away.

Number porting is free! You will not be required to pay a fee to port a number to or from a carrier including Tesix.

Is the MEID and IMEI that same?

While the numbers are similar, they are different numbers. Your MEID is most commonly used with CDMA carriers. The IMEI are used on GSM carriers. The IMEI: An International Mobile Station Equipment Identity (IMEI) number is a 15-digit number which is different with every smartphone. It is a way to uniquely identify a specific iPhone or Android, even yours. The MEID: MEID is a unique 14-digit number that is a unique identifier of a specific cell phone. For easy remembering, a phone’s MEID number is a phone’s IMEI number minus the last digit if it has both. Any phones that use the CDMA system and have Sprint, Verizon, or U.S. Cellular cellular plans have an MEID number. So, now that you know what IMEI and MEID is, what’s the difference?

The APN and VPN is not the same. A virtual private network (VPN) is programming that creates a safe and encrypted connection over a less secure network, such as the public internet.

An Access Point Name (APN) is the name of a gateway between a GSM, GPRS, 3G or 4G mobile network and another computer network, frequently the public Internet. A mobile device making a data connection must be configured with an APN to present to the carrier. With Tesix, a VPN is not a necessary only the APN is crucial to your device working success.

Will my APN configure on its own?

Not always. Some devices require manual configuration on its APN. Android devices will sometimes need manual APN configurations but Apple devices will kick in on their own as they do not have a APN configuration slot.
