Cell phones from nearly every manufacturer will work on our network as long as they are 4G VoLTE or 5G compatible and use a SIM card. If you already have a compatible phone, all you need to do is purchase an Ultra Mobile SIM kit.

If your 4G VoLTE or 5G compatible phone meets the following two criteria, your phone will work with Ultra Mobile:

1. Your phone requires a SIM card.
2. You have an unlocked phone.

If you begin your Ultra Mobile registration and your phone says, “Restricted” or “Contact Service Provider,” doesn’t allow you to make calls, or won’t grant access to your phone book, the phone is most likely locked. Contact your previous carrier to unlock your phone.

Ultra Mobile has partnered with one of the fastest voice and 5G • 4G LTE networks in the country! View our Coverage Map to find out if there is coverage in your area.

Our high-speed data will always attempt 5G • 4G LTE speeds, but certain locations or network conditions will render 5G • 4G LTE unavailable. Your network speed will be dependent on your location, coverage and device.

After the allotted 5G • 4G LTE data is exhausted, data speeds will be slowed. Further throttling may occur for heavy data users. For any questions about data speed, please refer to our Terms and Conditions.

You can shop for phones & SIMs from the impressive lineup on our website or visit a participating Ultra Mobile Retailer!

5G is the fifth generation of wireless network technology that will deliver faster download speeds and enhanced connectivity, providing us the potential to experience new, innovative technologies, and transform the way we live, work, and play.

5G isn’t replacing 4G any time soon. In fact, they will coexist and work together. 5G-capable phones can use both 4G and 5G technology.

5G is already available on Ultra Mobile to anyone with an Ultra plan and a 5G-capable phone to access our 5G network. 5G coverage varies nationwide and may not be available in your area.

5G simply increases the speed that you can download files. If a file requires 2MB of data to download it on 4G, it will still be 2MB of data to download it on 5G. You may just finish downloading it faster.

If your plan allows you 1GB of 5G • 4G LTE of data per month, then you’ll have 1GB of data to use at the fastest speed possible at the time, whether it’s 4G or 5G.

To bring your 5G capable phone to Ultra Mobile, it must be unlocked and VoLTE compatible. To check compatibility, please visit: https://www.ultramobile.com/byop/#

No, there is no need to change your plan. As long as your phone is compatible, you’ll be able to enjoy the improved experience regardless of your plan.

You should ensure the phone you’re buying includes 4G LTE with VoLTE or 5G. A device with bands 2, 4, 12, and 71 is best. Visit ultramobile.com/phones to shop compatible phones.

Yes. You can use the mobile hotspot on your 5G smartphones the same way you do with LTE. Hotspot usage draws from your monthly data allotment.

If your device is compatible and you’ve had no recent issues you should be all set. If you’re having issues with calls or texts, it might be a good idea to take a few more steps:

1. Check to see if there are any software updates for your phone that have not been installed.
2. Ensure that VoLTE is turned on. While the naming conventions may vary, the easiest way to see if VoLTE is enabled on your phone is to check within the device’s settings: Click on the Settings icon -> click ????-> type “volte” -> click VoLTE Calls Menu -> switch the VoLTE Call Toggle to “On.” If after typing “VoLTE” no menu option appears, the device either does not support VoLTE or VoLTE is defaulted to “On” which is likely if the phone is fairly new.
3. Confirm the APN settings for the device.

You’ll access a nationwide 5G network you can rely on to keep you connected in more places. Our 5G coverage utilizes a 600MHz low band signal that reaches more cities and towns across America (based on analysis of leading 5G networks, July 2020).

A 5G indicator will appear when a 5G capable device is within range of a 5G signal, even if the device is not in use.

Just go to the settings menu on your phone and select “System Updates.” Or, “About Phone / About Device,” then “System Updates,” “Update Android” or “Check Now.”

This year, all major nationwide wireless providers are shutting down their 3G networks to open up valuable space for 4G and 5G networks.

What is 3G?

3G was the former standard for the way cellphones operated and connected to the internet. When it first launched, 3G was what enabled us to have access to the internet via our smartphones. The name 3G refers to it being the third generation of tech that allows our phones to connect to the internet.

Why is the 3G shutdown happening?

Nowadays, 3G networks are outdated. They also take up valuable space that 4G and 5G networks rely on since there are limited frequencies for wireless providers to use. Also, 3G isn’t very cost-effective and can even drain your phone’s battery quicker, among other problems. That’s why the 3G shutdown is positive–it makes room for 4G and 5G technologies, which are faster and more efficient. 4G and 5G are better for you and your phone.

When will 3G be shutdown and will I be impacted?

When the shutdown happens, any phones that run exclusively on these older 3G networks will no longer be able to make or receive calls or use other data services. If you’re an Ultra Mobile
customer, T-Mobile’s older 3G network will shutdown on July 1, 2022. If you’re an impacted subscriber, you will be notified.

You may be impacted by the 3G shutdown if:

You use a 3G exclusive device that is non-voice over long-term evolution (VoLTE) compatible
You have a 4G device that doesn’t allow you to enable VoLTE

Here’s how to enable VoLTE if your phone allows you to do so:

How to Turn on VoLTE on iPhones

Open Settings
Tap Cellular
Tap Cellular Data Options
Under Voice & Data, make sure VoLTE is selected

How to Turn on VoLTE on Samsung (most devices)

Open Settings
Tap Network & Internet
Tap Preferred Network Type
Turn on VoLTE calls

How to Turn on VoLTE on most other Android devices

The easiest way to see if VoLTE is enabled on your Android phone is to check your phone’s Settings. Tap Settings > tap the search icon -> type “volte” -> select VoLTE Calls Menu -> make sure the toggle is switched to on. If you type “VoLTE” and no option appears, the device probably isn’t compatible with VoLTE or it may be defaulted to On if it’s a newer device.

If you have a 3G exclusive device or a 4G device that doesn’t allow you to enable VoLTE, you’ll want to switch to a 4G device that is VoLTE-capable or a 5G device. If you need a new device, please visit our phone store or an Ultra Retailer.

Unfortunately, Ultra plans do not support smartwatches right now.

Yes. Just follow these easy steps:

1) Visit the Google Play Store

2) Search “Messages” by Google LLC

3) Download and open the Messages app

4) When prompted to change your default messaging app, follow the onscreen instructions, and click “yes” to make it your default browser

5) Go into your device settings to enable the Chat feature

With RCS, Android users now have access to key features that Apple’s iMessage users have had for years, including read receipts that tell users when people they’re chatting with have seen their messages, the ability to send richer media, like high-resolution images, and typing bubbles that let users see when the person they’re chatting with is typing a message.

Note: RCS only applies to Android 6.0 and up. RCS requires a data connection (either WiFi or cellular). Both the sender and the recipient must have RCS enabled in order to send messages through RCS.
