Frequently Asked Questions
Many wireless service providers put software “locks” on smartphones to ensure the devices can only be used on specific networks. This limits the user’s ability to use the device on a competing network unless it is unlocked. Unlocked smartphones do not have restrictive software locks, allowing consumers to choose network providers the same way they choose devices: based on price and features.
NUU’s unlocked Android™ smartphones provide an alternative option to rigid, long-term contracts for mobile consumers by offering smartphones with the latest technology, increased flexibility and exceptional quality at more accessible prices.
Devices sold through service providers are often heavily discounted in exchange for a required contract, often years in length and subject to termination fees if the customer decides to cancel. Software locks ensure the devices will be active for a specific period of time on the network of the provider that has subsidized the device purchase price.
Unlocked smartphones from NUU allow for portability between most networks at an affordable price, without sacrificing quality or performance. NUU offers a variety of models for every need and budget – from the entry-level A11L, A23 Plus and F4L to the lifestyle-minded B10 and X6 Plus models, or the luxury A25 and B20 5G.
Maybe. International calling features depend on the carrier network, the country where you’ll be using the device and whether you want voice, data or both. Because unlocked smartphones can be used on a variety of carrier networks, it’s always best to check with the carrier about international connectivity.
The biggest advantage of having an unlocked phone is the freedom to choose a carrier without signing a long-term contract. This is especially attractive for consumers who like to “shop around” for the best carrier deals and don’t want to be restricted by costly termination fees.
NUU unlocked smartphones are perfect for people who are new to smartphones, want the freedom to choose a carrier without a long-term contract, or want all the features of an expensive brand at a more reasonable price.
That depends on which carrier you’re using. Different carrier networks use different technologies for connectivity, and these technologies vary by region and country. Because each network is different, your device may not work across all carriers, or certain features may not work well (if at all).
NUU unlocked Android smartphones are compatible with major North American carrier networks, including T-Mobile, AT&T, Allvoi Wireless, Beast Mobile, Best Cellular, Boom! Mobile, Boost Mobile, Boss Wireless, Consumer Cellular, EarthLink Mobile, Gen Mobile, Google Fi, GoSmart Mobile, Hello Mobile, Kroger Wireless, Lycamobile, Mango Mobile, Metro By T-Mobile, Mint Mobile, Net10, Optimum Mobile, Patriot Mobile, Red Pocket Mobile, Republic Wireless, Simple Mobile, SpeedTalk Mobile, Straight Talk, Tello, TextNow, Ting Mobile, Tracfone, Ultra Mobile, UNREAL Mobile, US Mobile, Walmart Family Mobile and many more. Please check with your carrier directly for more information on their Bring Your Own Device program compatibility.
No. Your device must be compatible with the network technology used by the carrier. Devices are optimized to work with service providers’ specific networks and will not work across non-compatible networks.
No. For prepaid phones, it’s the carrier network costs that are prepaid. Prepaid devices are tied to a specific network and carrier, while unlocked phones can be activated on any compatible network.
It depends on the model selected. NUU uses the most current Android™ OS when manufacturing their devices. Newer unlocked devices like the NUU A23 Plus, A15 and A25 are built on the Android™ 13 operating system.
Absolutely! Depending on the model and price, unlocked Android™ smartphones from NUU are available with high-quality front and rear cameras, high resolution displays, speedy MediaTek processors, dual SIM cards, expandable microSD™ memory slots and batteries (with offering fast charging function).
Yes. Depending on the carrier network technology, unlocked smartphones offer the same connection speed and performance as locked devices.

Briefly, though, inserting a SIM works like so:
1. Power off the phone
2. Carefully pry open the case
3. Remove the battery
4. Insert the SIM according to the diagram
5. Put the battery back in
6. Power on the phone
Hold the Power button for 2 seconds
Make sure your unit is plugged in and charging
Verify the battery is properly installed
On your home screen, tap “Settings”. Scroll down and select “About Phone”. Then tap “System Update”. If updates are available, you’ll see them here.
This is likely related to your SIM card or network availability. If your signal is very weak, contact your carrier to make sure they have enough coverage in the area. This will help eliminate the carrier as a variable.
If you set up your Google account on your phone, you can access Google’s Android Device Manager (https://www.google.com/android/devicemanager) in order to forcibly reset your Lock screen password.

Check to see how many apps you have running as this can quickly drain your battery.
Go to SETTINGS > DEVICE > BATTERY for a list of which apps use how much battery. You may need to adjust app settings to compensate.
You can use the “Recent Apps” Menu to close your apps. Making this a common habit will greatly increase your battery usage.
You can expect your NUU Smartphone to get you through the work day with moderate to heavy usage.
Close any apps you are not using, as many background apps can take up valuable resources required for speedy operation.
You can also go to SETTINGS > APPLICATIONS and move some applications to the MicroSD Card to help free up space.
There are many 3rd party apps that can help monitor usage and ensure unnecessary apps are not running.
Check to make sure your PREFERRED SIM SETTINGS are set to the correct SIM card slot. You can verify this by tapping SETTINGS> Dual SIM settings.
The B15 and B10 supports USB OTG.
