If you miss a payment, they delete your number forever
Our virtual lives are built around our phone numbers. They are the backup keys to our entire online presence, not to mention the main way many people contact us. Losing a number can mean losing access across the internet.
If you miss a payment in Tello, they simply delete your number. This is irreversible. I just lost a number that I had used for more than a decade. Just gone. If you care about yourself, find a cellular provider who takes their customers seriously.
To be fair, they were OK before killing my number, so I'll give them one extra star.
Your Spanish speaking customer service. This time I think it was Lucía, but before I had also the pleasure of speaking to somebody from Bolivia

Great Company, Great Service
Amazing service. Simple, no ads or spam mail, super cheap, and I get exactly what I want.
Makes me feel like big phone companies are a scam. I would recommend Tello to anyone.

Great company
The fact that I could reach a 'Customer Service Person' rather than recorded messages was excellent. Your customer service personnel are the most helpful, professional and accommodating people I have had the pleasure of dealing with. Yes, I had an issue with my Tello sim card but your customer service lady had it sorted in no time at all. Lovely people to deal with.

We have been having the same issue for…
We have been having the same issue for three days now. When we log into our account nothing is getting updated pertaining to data usage or minute used. We have called several times and nobody has helped. My last call We were given a case number and was told they will email us when problem is fixed. Should be within 24 hours. Time will tell as the clock is ticking and still no updates from Tello or my usage on my paid account.

Dear James,
We understand your concern about the usage information not appearing correctly in your account, and we’re sorry for the inconvenience this has caused.
While it is normal for usage records to sometimes take up to 48 hours to update, we understand that this has been ongoing for a few days. We can assure you that your case is being reviewed by our technical team, and we’ll contact you as soon as we have any updates.
Thank you for your patience and understanding while we work to resolve this.
I just got a new unlocked phone, and the set up was, overall, super easy, IMEI number, plan selection, Tello cancelled my previous phone's plan. I didn't have to ask for anything... I am so happy I found Tello a few years ago... Great plan prices, the Service. Other carriers would charge extra for some of what Tello offers, but not Tello. They just show up and deliver what they promise.

AVOID AT ALL COSTS-POOR CUSTOMER SERVICE
Sometimes a great rate isn't worth it.
I had Tello for years, and I loved them, but a lot has changed in the last year. No customer service, no working support phone number, no chat. Emails are the only form of support, which I detest. You're in the middle of setting up an account with them, you have a problem, and you have to wait for an email? No thanks.
I can't activate the E SIM, and there's no help, so I have no phone. AVOID AT ALL COSTS! Update, my phone doesn't accept E-SIM, so now I have to wait for a SIM card. It looks like they charged me for both. Tello did answer my emails the following dat, saying to contact them by email or phone if I need more help. They gave me the same two numbers that I found by Googling them the day before and neither worked. Rings and goes dead. Beyond frustrating.

Dear Darla,
Thank you for your feedback. Please note that to use our eSIMs, devices must be fully unlocked by your primary carrier.
We have reached out to you via email with information on how to check your device status, as well as the complete steps for activation. Once your carrier unlocks the device, you should be able to complete the setup smoothly. Please reply directly to our message if you require additional support.

Very good service
Very good service, plenty of data for my needs, and half price of anything else comparable.
I hate that I run out of data so fast and that I have to pay extra for spam blocking but it is affordable but sometimes I don’t have money to add data and that’s unfortunate
Bought an iPhone cuz my android was a few years old...seamless switch! Love tello!!

Josue was so helpful
Josue was so helpful. I wasn't clear on what I wanted and he was able to give me information and ask me the right questions in a patient manner until I made a decision on a product and plan. I appreciated his going the extra mile and giving me suggestions or other options to consider. I was initially thinking of using the SIM for one month but am now interested in keeping it and using it during my travels. As an HR Director, I recommend you keep a great employee like Josue. In fact give him a promotion and a raise. Such employees need to be recognised and appreciated.
