I bought this service for my child. IT HAS NOT WORKED SINCE WE HAD IT. I got it so he could text and talk and he can only get text 3 people ( no idea why) and its all android devices when he has i phone. I have called in a few times and they think they fix it and they never did. My son has told me it has not worked since we have changed to this plan. I have paid for him to be able to get text from 3 people. I have not heard back from the company at all. The last *** tried and nothing worked, He still was unable to get recieve texts and sometimes calls ( callsonly in wifi). I want a refund and to service ended immediately.Business Response

I submitted a port-in request from T-Mobile to Tello on July 19. On the same day I received a suspension email from T-Mobile confirming that the number had been successfully ported out. However, on July 21, Tello claimed that the port-in request was rejected by the previous carrier.I immediately contacted T-Mobile, who confirmed multiple times that the number has already been released and is no longer with them. Meanwhile, Tellos system has not updated, and their technical team is still reviewing the ******** of today (July 22), the number is still not active on Tello. I am traveling internationally tonight, and this delay is causing serious disruption to my access to two-factor authentication and other important communications.I have provided all required information, including the account number, port PIN, billing address. Still, ********************** has not resolved the issue in a timely manner, nor have they provided a clear path forward.I am requesting immediate escalation and resolution, and Im filing this complaint due to negligence and poor customer support on *********************** part.Business Response
Date: 07/23/2025
Dear customer,
The port-in request experienced unforeseen technical issues during provisioning. As soon as the issue was identified, the case was properly
escalated to our technical team and the previous carrier for resolution.
Based on our logs we can see our Customer Support team explained the situation, and even offered compensation for the inconvenience.
Unfortunately, this issue cannot be manually corrected on our end, and we must wait for the escalation to be resolved on our providers end. In
the meantime, we are closely monitoring the case and remain committed to providing timely updates.We appreciate your understanding!

I registered tello with my ****** account on July 20. After registration, I paid for an 8 USD package, but my account was suspended.

If not, please cancel my account. Because I used a ****** account to register the account, ********************** has no right to lock my ****** account. Please release my ****** account.Business Response

I am rejecting this response because:Hello, thank you for your reply.
I have checked your company's usage rules and I want to file an appeal. First of all, this is my first time registering tello. In addition, I registered through a Chinese customer link. I don't know if he violated the rules, but I didn't. I registered tello only to contact customers, not to engage in fraud or violate national laws and policies, so I request to restore the right to use.

After Tello failed to successfully port my CenturyLink number I tried to delete my Tello account. I found the link on their web site to delete an account was broken, it simply shows the support screen.There's no way Tello doesn't know the delete account link doesn't work. They are doing this to reduce departures while likely violating California state law.Business Response
Date: 06/30/2025
Hello ****,
We apologize for the inconvenience. The link is not broken, and it is
only asking you to either port out the temporary number or request its
deletion, just like we advised in the follow-up email we sent to you.
We usually ask for confirmation from our customers to avoid expiring a
number accidentally, even if it is only the temporary one.
We have now expired your number, and you should be able to delete the account with the very same link you had.
Please let us know if you need further assistance.Initial Complaint

Dear BBB,Tello, my mobile provider, deactivated my numbers without notice. When I contacted them, I was told I could port out but only if I provided the Security PIN, which I forgot.However, they said the only way to reset the PIN is by receiving an SMS to one of my blocked numbers: ************** ************** This is a catch-22 situation: they require access to something they themselves have denied. They refuse to offer alternative methods for verification or PIN reset. I believe this is unethical and blocks fair access to *************: ****** ********* DOB: ********** Address: ***************************** Thank you for your help,****** *********Business Response
