Warp Speed on 5GWarp Speed on 5GWarp Speed on 5G

5G-enabled devices can expect fast 5G speeds in areas where 5G networks are available. Dynamic Spectrum-Sharing (DSS) technology means that your device will run simultaneously on 4G LTE networks.

We offer 5G speeds over both of our networks, depending on coverage and compatibility of both device hardware and up-to-date software.

You can see a list of all 5G devices here, and selection of some of those 5G devices in our shop.

Switching to US Mobile's plans is quick and simple. You don't have to buy a new phone, since you can bring your device to US Mobile. You can keep your old number. All you really need to get is our prepaid SIM Starter Kit or an eSIM capable phone. Once you have that you can switch your phone service to US Mobile in as little as 2-3 minutes. See how easy it is to switch to US Mobile.

You automatically get access to 5G on all plans with a compatible device. If you want to know more on where to get coverage, reach out to customer support.

Currently, you can make international calls to 200+ destinations on either of our networks. It is included on all our annual plans, on our By the Gig shareable plans, and on our monthly Premium plan. International calling can also be purchased as an add-on on our Light and Monthly Starter plan. Note that international calling only works on our domestic (US) SIMs; if you have purchased one of our international data eSIMs, those do not support calling.

You need a 5G-enabled device (like an iPhone 12 or a Samsung Galaxy S21 Ultra) and need to be in an area where your network of choice (Dark Star, Warp, or Light Speed) has 5G coverage. This coverage area will expand in the months and years to come, so we’ll keep you posted.

We provide 5G and 4G LTE coverage on all three major networks in the US. You can read more about our networks, and coverage here. Or you can just ask us!

Warp Speed 5G uses technology like millimeter wave (mmWave) and Massive MIMO (Multiple Input Multiple Output) to transmit more data more efficiently. mmWave is a new type of frequency band that uses much smaller wavelengths to transmit data. Smaller wavelengths means more data can be transmitted in the same amount of time. Massive MIMO—an expansion of MIMO that was used to get Ludicrous speeds on LTE—not only uses a lot more (massive) number of antennas concentrated together but also more complex designs to focus energy. Where available, these technologies work in conjunction with more antennas that are even more sophisticated antennas in some devices to get you Warp Speeds.

Yes! All our phone plans, on all three of our networks (Dark Star, Warp, and Light Speed) come with WiFi Calling at no extra cost to you.
