Hello Robert, We are sorry to hear about your frustration, but we would like to clarify what happened with your service. Tello is a mobile service provider and does not push software updates to individual mobile devices—software updates are controlled entirely by your device’s manufacturer. Regarding device compatibility: your Xiaomi Redmi A5 was not manufactured for the US market. While non-US devices may sometimes pick up basic network signals temporarily, they lack the full set of cellular bands required to maintain a reliable, consistent connection on US networks. Over time, or during network adjustments, these devices often struggle to stay connected, which can cause service to drop or switch between signal types. Additionally, on the day of your call, our underlying network provider experienced a widespread regional outage that temporarily impacted service for many users across the country, regardless of their device. Our support team provided accurate information regarding your device's compatibility and network limitations. We hold our team to high standards of professionalism and expect the same mutual respect during customer interactions. If you decide to switch to a fully US-compatible device in the future, we would be happy to assist you. Best regards, Tello

Dear Charles, Thank you for your feedback. Due to high call volumes today, phone wait times have been longer than usual. We searched our records and found no prior emails received from your account. For future reference, our official email channel is [email protected]. To resolve your eSIM activation issue, a specialist has already been assigned to reach out to you by phone shortly.
