What's included in my Tello plan?
International Calling
All Tello plans (except for data-only plans) include calls to more than 60 countries as well as the US... at no extra cost! So, for example, if you make a 20-minute call to Canada, that 20 minutes come out of your monthly minutes' balance. Overseas freephone numbers may not be available.
5G
5G is available to anyone with a Tello plan, a 5G-capable phone and located in an area that provides 5G coverage (see our Coverage map). Your service will switch seamlessly between 5G and 4G/LTE, whichever signal is stronger.
Hotspot
Our plans also include the mobile Hotspot feature at no extra charge. The data you use via Hotspot just pulls from your monthly Data balance. All you need is a Hotspot-capable phone.
When your data plan balance runs out and your Pay As You Go balance falls below $0.50, hotspot is automatically disabled.
When using the Unlimited Data plan, you have 5 GB of hotspot included.
Travel Options
We have quite a few travel options for calling and texting when you are traveling abroad:- Roaming -- With Tello you can benefit from international roaming in 250+ countries and territories. Roaming calls, texting, and data costs are charged from your Pay As You Go balance, so you need a minimum of $5 Pay As You Go credit in order to activate international roaming. This can be done from your account -> My Settings.
- Wi-Fi Calling & Text -- This is a feature available on the vast majority of Tello-compatible phones and you can check your phone settings to confirm. It allows for calling & texting via the closest available Wi-Fi network which could be at a hotel, your office, at home, or even a Wi-Fi Hotspot. For more details check out our blog.
- "My Tello" App --You also have the option of using our free "My Tello" app to make calls through Wi-Fi. You can not receive calls via the App and texting is also not available via the App - this can only be used to make calls. The "My Tello" app is a free download for iOS and Android users.
3-Way Calling
3-Way calling is available and allows you to add a third party to a call so that all three parties may talk to each other simultaneously.
Visual Voicemail
Visual Voicemail is only available for Android users on our network at the moment. If your Android phone does not natively support Visual Voicemail, you can download and use a third-party app available in Google Play Store.
Toll-Free Calls
Calls to all Toll-Free Numbers in the USA are charged from your voice balance as normal.
2FA
Shortcodes and 2-factor authentication messages can be received on your Tello line.
Note:
Tello does not provide a 411 directory assistance service. -
Where can I find the account details needed to port out?
For security reasons, all customers are required to retrieve their porting information (Tello Account Number & Temporary Port Out PIN) directly from their own online account. (this feature is not available in the "My Tello" App)
- Go to the "Porting" tab in your online account
- Scroll down to the "Port Out" section and click "Information"
- Click on the "Retrieve Port Out Information" button
- Provide the required information.

What APN settings are needed with Tello?
When you activate the service with Tello, all your APN settings are usually set automatically.
However, if you're having issues with data, hotspot, MMS or group messaging, you need to check your APN settings to make sure that they're correct.
On an Android device, you can view and adjust your APN settings in the following location:- Settings
- Tap More networks (under the Connections tab, or More, Wireless & networks, Wireless Controls, Wireless Manager, Phone Information).
- Select Mobile or Cellular networks.
- Choose Access Point Names.
- Tap the Menu icon.
- Tap the Access Point you would like to check.
- If you're adding a new APN, tap New APN and enter the following APN: wholesale
Save the APN, restart the device, and test the service.
On an iOS device, you can view or adjust your APN settings in one of the following locations:- Settings > Cellular > Cellular Data Options > Cellular Network OR
- Settings > Mobile Data > Mobile Data Options > Mobile Data Network.
Here are the APN settings required when using an iOS device on Tello:- Mobile Data
- APN: wholesale
- MMS
- APN: service
- MMSC: http://wholesale.mmsmvno.com/mms/wapenc

How can I use Wi-Fi Calling?
Wi-Fi Calling & Text is included with your Tello service.
This feature is available on the vast majority of Tello-compatible phones and you can check your own phone settings to confirm. It allows for calling & texting via the closest available Wi-Fi network which could be at a hotel, your office, at home, or even a Wi-Fi hotspot.
It is an ideal alternative to roaming when you are traveling abroad or even when you experience poor network coverage at home in the US.
You can use Wi-Fi Calling with Tello if the following conditions are met:- your device supports Wi-Fi Calling which the majority of Tello-compatible phones do.
- you have enabled Wi-Fi Calling on the device.
- you have registered an E911 address in your Tello online account (or through your phone Menu).
- the Wi-Fi network you are using allows Wi-Fi Calling. Obviously, this is not within Tello's control or responsibility.
How is Wi-Fi Calling & Texting Charged?
Wi-Fi Calling & Texting has no additional charge.
It's simply taken from your existing plan balance or your Pay As You Go balance, whichever applies to the activity.
For example, if you receive any calls (no matter where from) or if you call the US or any of the 60+ included international destinations then the minutes of those calls will be deducted from your minutes' plan balance.
If, on the other hand, you call an international destination that is not included in our plans (Ex: Cuba), then it will be charged from your Pay As You Go balance if you have one.
The same logic applies to Wi-Fi Text.
One-Time Passwords (OTPs)
You can receive any kind of text message if you have successfully set up Wi-Fi Calling & Text.
This includes, one-time passwords (OTPs) and short codes for verification and 2-factor authentication.
If Wi-Fi calling & text is working for you while abroad and you’re receiving SMS's as usual, there should be no problem for you to get texts from your bank for verification.
However, of course, MMS will not work.
Please check our International Calling page for included countries and the rates for excluded countries.
Also, please visit our Blog for more details about Wi-Fi Calling & Text.

How can I bring my current phone number over to Tello?
Transferring your number to Tello is fast and easy (and free) but for security reasons, it must be made via your online account only. (This feature is not available in the "My Tello" App).
Firstly, you need to ensure that, you have purchased, received, and successfully activated your new Tello SIM or either purchased and activated your Tello eSIM in your online account.
If you have not done so already, go to https://tello.com/activate and follow the prompts to activate the service.
Once you have successfully activated the Tello service, follow the steps below to start the number transfer process.
Submit your number transfer request directly from: https://tello.com/account/port_in.
(The port in form will only become available & visible after successful SIM activation.)
- Enter the phone number you wish to transfer and click "Check" - If the number can be ported, you will be prompted to fill in the port-in details and follow the prompts.
Note:
If you have not done so already, you will need to contact your current provider to retrieve the following information directly from them:- Account number from current provider
- PIN number from current provider
- Your address as listed on the phone bill
- First name and last name as listed on the phone bill
Consult our "Carrier Transfer Information" to help guide you in the right direction.
The speed of the port-in process depends on your current provider and can take anywhere from 2 hours to 2 working days for regular mobile numbers and up to 5 working days for landline and VOIP numbers.
If any of the information submitted is invalid and is not corrected by you within 3 business days we may cancel the port request.
Once the port in is submitted, any notification about the port in status will be sent to the email address you registered with Tello.
Note:
- Even after your number has been successfully ported to Tello, it may take up to 3 business days before your ported number is reflected correctly as your Caller ID.
- If 3 business days pass after the successful porting, and your Caller ID still shows the wrong number, please email our Support team with the details.

- Press and hold the 1 key or dial 123 on your device.
- You will be automatically connected to your voice mailbox and be prompted to enter your password.
