How is the Network Coverage and Speed?
While they don’t list percentages, access to Sprint’s nationwide 4G network brings coverage for more than 280-million Americans. We’ll use their network for the following benchmarks.
You can check coverage and network types in your area on their Coverage Map.
Notable considerations include:
- As they do not have roaming agreements with other providers, you may find yourself without service in areas without a strong Sprint network presence.
In PC Magazine's 2018 "Fastest Mobile Networks" study, Sprint's network was near the bottom for national download speed averages. However, they were the fastest network in Philadelphia, St. Louis, Oklahoma City, Houston, and Seattle.
In PC Magazine's 2017 "Fastest Mobile Networks" study, Sprint's network ranked last. Download speeds averaged 20.5Mbps while uploads clocked in at 6.5Mbps--roughly half the speed of competing networks.
The network also ranked last in Ookla's "2018 United States SpeedTest Market Report" with a SpeedScore of 20.38 -- up almost 5 points from their 2017 score of 15.39.
OpenSignal's July 2018 "State of Mobile Networks: USA" report also ranks them last for 4G upload and download speeds with average speeds of 14Mbps down and 3Mbps up on 4G. For 3G download speeds, they edged out Verizon for the #3 spot at just over 1Mbps.
Do They Charge Roaming Fees?
No. However, this comes with an important distinction--they don’t offer domestic or international roaming either. If you’re not within the coverage area, your only option for service is Wi-Fi calling through the My Tello app.
What About Long Distance Fees?
All plans include calls within the United States, Canada, Mexico, and China. International calls are billed separately from prepaid plans using pay-as-you-go credit.
Rates to other countries vary. However, they offer a simple calculator to see how many minutes or texts a pay-as-you-go card is worth based on your calling destination.
Does Tello Offer Wi-Fi Calling?
Yes. You can place Wi-Fi calls using the My Tello app for iOS and Android.
How About Voice over LTE (VoLTE)?
Can I Tether My Phone?
Yes! All plans include tethering if the phone supports the feature. Tethering data counts toward your 4G data allotment. Once you deplete your high-speed data, speeds throttle to 64kbps--slightly faster than dial-up.
Can I Rollover Unused Data?
While Tello does not offer month-to-month data rollover, they will allow you to rollover data when upgrading or downgrading plans. Plan changes are free and any unused minutes or data are added instantly and available for 30 days from the date of changing your plan.
What Add-ons or Bundles are Available?
With their a la carte pricing method for monthly plans, there is no need for add-ons or bundles. If your plan doesn’t suit your needs, simply upgrade or downgrade your voice, text or data allotment. There’s no fee to change your plan and you’ll be billed immediately to reflect the difference between plans.
Can I Bring My Own Device?
Yes! However, it is important to note they use a different network type from many major US carriers--CDMA. In many cases, Sprint-compatible phones work with Tello. However, if you’re trying to bring a phone from one of the other carriers--or you purchased an unlocked phone online--you’ll want to contact their customer care team to ensure compatibility before signing up.
Do They Require a Credit Check?
This carrier does perform checks for new lines of service. At the time of writing, this is a "soft" check--meaning the check should not impact your credit report.
To run the credit check, the carrier will need:
- Your name
- Current address
In some cases, a government-issued ID--such as a Driver's License, State Identification Card or Passport--is required as well.
NOTE: Credit checks from carriers that pull your credit bureau report may impact your credit score. If you're not sure the best options for your credit profile, we suggest contacting the carrier directly before attempting to obtain service.
What About Activation and SIM Fees?
Tello does not charge activation fees.
If you bring your own phone or tablet, you'll also need a Tello SIM.
SIM kits are available through their online store for $9.99.
Do They Charge an Early Termination Fee?
No! Monthly plans have no term commitments and devices are purchased upfront. This means no worry about surprise fees should you switch providers.
Can I Port My Number To or From Tello?
Yes! They support porting numbers from any area in which Wireless Number Portability is in effect.
To start the porting process, you’ll need some information. Common items include:
- The phone number you wish to port
- The carrier with which the number is currently assigned
- The account number with that carrier
- The PIN or security password for that account
- The billing address listed on that account
- The first and last name of the account holder
You can find out more about the process at their Help Center.
Will They Unlock My Phone?
All phones sold by Tello are unlocked when you receive them.
