Ultra Mobile has both single-month plans and multi-month plans depending on what you are able to pay for upfront. There are a few differences between the two sets of plans beyond the price, however, starting with international calling and roaming credits. The single-month unlimited plan also gets more data before throttling at 50GB compared to 32GB on the multi-month option. Limited data on unlimited plans isn't exclusive to Ultra Mobile but is a consideration for heavy users. Still, either option is well above what people typically use and there are no overage fees.

Ultra Mobile's Single-Month Plans

Plan Base Price Auto-Recharge discount Talk and Text Hotspot International credit

Ultra Mobile has a fairly wide range of plans depending on what you need with international features on most of them. Additional high-speed data can be added to these plans at 1GB for $10 and 3GB for $20. You can also add international roaming credit in $5, $10, and $20 increments. Add-ons can be purchased by signing into your online account, calling support, or by text on your Ultra Mobile phone. The single-month unlimited plan may also be subject to deprioritization after 1GB of usage.

Speaking of international credits, all of Ultra Mobile's plans include unlimited talk to more than 80 countries so your credits will only need to be used when calling countries not supported. The 80 regions include some of the most popular destinations such as Canada, Mexico, China, the United Kingdom, and South Korea. Visit Ultra Mobile's international calling page to find the rates for more destinations.

If you know you'll be sticking with Ultra Mobile for a while, you can save some money by signing up for a multi-month plan. Multi-month plans include calling to the same 80+ international destinations and hotspot capability. These plans lack any included international credits so those must be purchased separately if needed. The unlimited plan will also have video streams dropped to SD quality much of the time.

Ultra Mobile's Multi-Month Plans

Plan size 3 month 6 months 12 months
Unlimited (32GB) $46/mo. ($138) $45/mo. ($270) $40/mo. ($480)
6GB $28/mo. ($84) $27/mo. ($162) $25/mo. ($300)
3GB $22/mo. ($66) $21/mo. ($126) $20/mo. ($240)
1GB $16/mo. ($48) $15/mo. ($90) $10/mo. ($120)

The best value Ultra Mobile plan for most people will be one of the multi-month data plans at 3GB or 6GB. If you need a lot of data, the unlimited plan is still a competitive rate even compared to carriers without international features. Just keep in mind that the multi-month unlimited plan comes with less data at 32GB compared to 50GB on the single-month plan. Still, it's great to see a pure talk and text plan with international calling included.

Ultra's International Flex

Ultra Mobile is one of the best choices for a new or temporary resident in the U.S. thanks to included support for international calling. Ultra Mobile also has a tourist SIM available directly from T-Mobile stores. Whether you only need a few weeks or several months, Ultra Mobile has a great option available.

Ultra's uTalk is a $10 add-on feature that's compatible with all Ultra Mobile plans. UTalk adds 39 international calling destinations with up to 1250 minutes included. If you are looking for calling support to more countries and don't want to worry about adding calling credit, uTalk is a great addition.

Ultra Mobile Tourist is a SIM designed specifically for those visiting the United States. It comes with 3GB of high-speed data on the T-Mobile network, unlimited domestic talk, and text, and well 100 minutes of calling to Ultra's 80+ international destinations just like its other plans. This SIM lasts just three weeks, or 21 days, but should be a great fit for those that want to be in control of their phone service while visiting the U.S. as well as getting access to a U.S. phone number which can make things like booking reservations a whole lot easier.

Ultra's Flex plan isn't as simple as Ultra's other plans but can be a good fit for someone that doesn't need much data and wants to make a lot of calls to one of Ultra's Flex 15 Destinations. Unlimited calling is available to Brazil, Canada, China, France, Germany, Hong Kong, Ireland, Italy, Israel, Malaysia, Mexico, Singapore, South Korea, Thailand, and the United Kingdom. Unlimited nationwide talk and text are included as well as 500MB of high-speed data with rollover.

Flex starts at $22 per month but can be reduced down to $12.50 if you either pay for four months upfront or bring four lines. Data with rollover can be added as well at $5 for 500MB, $10 for 1GB, $20 for 2GB, $45 for 5GB, and $80 for 10GB. With these discounted data prices and rollover, Ultra Flex can be a great value for those that need this specific set of features.

Coverage and 5G

The T-Mobile network has some of the best coverage around with the largest 5G network with continued investment bringing 5G coverage to over 280 million people. Compared to the other carriers T-Mobile's 5G is available to more people and has great spectrum capacity thanks to its 2.5GHz Band N41. T-Mobile's LTE coverage is also quite strong though it falls short compared to its main rivals. In reality, most people should be covered by this network the vast majority of the time but if you find yourself in a rural area, you may encounter dead zones.

How does Ultra Mobile stack up?

Prepaid, data-focused carriers are springing up all over but one of the closest comparisons is Mint Mobile vs. Ultra Mobile. This is no accident as Ultra Mobile is Mint Mobile's parent company and the two share a lot of DNA. If you don't need all of the international features included with Ultra's plans, Mint Mobile is a great alternative.

Google Fi is another carrier with great international features but Fi focuses more on international travel with its data rates carrying over to hundreds of countries. Google Fi also supports eSIM on a handful of the best Android phones such as the Pixel 5 allowing for easier configuration of multiple SIMs if you have a phone number for another country.

Finally, Visible is a low-cost unlimited plan that uses Verizon's network. Visible has very few international features apart from free calling to a handful of countries including Canada and Mexico. Still, you get great coverage in the U.S. with unlimited data including hotspot support if you're trying to get by without paying for home Wi-Fi. Visible costs $40 per month with the option of bringing the cost down to $25 per month when you sign up for Visible's Party Pay feature.
