Tel Phone number change tips:

Because of Chinese companies: China Telecom Group dislikes old customers and the cost is too low. And unilaterally lied, breached the contract and took back the phone number (2905-8260) and related services.

Therefore, China Telecom may illegally withdraw phone numbers and other services. But we still continue to try to keep the phone.

Thank you for your understanding and support. You are welcome to use email to keep in touch.
