What Ultra Mobile is and who uses it
Ultra Mobile is a wireless carrier that runs on the T-Mobile network. You buy a phone plan from Ultra Mobile, but your calls, texts, and data travel over T-Mobile's towers. Ultra Mobile does not own or maintain those towers — it pays T-Mobile for access to them. This arrangement is called an MVNO, or mobile virtual network operator.
Ultra Mobile markets itself to people who want lower monthly costs than T-Mobile's standard plans, or who need a plan that works month-to-month without a contract. The trade-off is that during times when T-Mobile's network is very busy, Ultra Mobile customers may experience slower data speeds than T-Mobile's own customers, because T-Mobile prioritizes its direct customers first.
Ultra Mobile also sells plans designed for people who travel internationally or who need to use a phone in multiple countries. Some of its plans include data in other nations at no extra charge per gigabyte, which can save money if you travel often.
Key Takeaways
- Ultra Mobile runs on T-Mobile's network but charges less than T-Mobile's standard plans because it does not own the network infrastructure.
- Plans are month-to-month with no contract, so you can cancel or change your plan each month without penalty.
- During peak network congestion, Ultra Mobile data may be slower than T-Mobile's own customers because T-Mobile prioritizes its direct subscribers.
- Ultra Mobile offers plans with international data included, which may cost less than buying international data from other carriers.
- You can bring your own phone to Ultra Mobile if it is unlocked and compatible with T-Mobile's network bands.
How to check if your phone works with Ultra Mobile
Ultra Mobile uses T-Mobile's network, so your phone must be compatible with T-Mobile's technology. The easiest way to check is to visit Ultra Mobile's website and enter your phone's model number or IMEI (a unique identifier on every phone). Ultra Mobile will tell you whether that phone will work on its network.
If you own the phone outright and it is unlocked, you have a better chance of compatibility than if it is locked to another carrier. A locked phone will not work on Ultra Mobile even if the hardware is compatible. You can ask your current carrier to unlock your phone — most carriers will do this if you have paid off the device and your account is in good standing.
If you do not have a compatible phone, Ultra Mobile sells phones directly. These are usually less expensive than buying from T-Mobile or a retail store, but you should compare prices before you buy.
Ultra Mobile plan types and what they include
Ultra Mobile offers several plan categories. Pay-as-you-go plans charge you per minute, text, and megabyte of data — useful if you use your phone very little. Monthly plans give you a set amount of talk, text, and data each month for a flat fee. International plans include data and calling in other countries at rates lower than standard roaming charges.
Monthly plans vary in how much data they include, from plans with 1 GB per month to plans with 10 GB or more. The more data you choose, the higher your monthly cost. Ultra Mobile also offers plans with unlimited talk and text but limited data, which can be cheaper if you mainly use your phone for calls and messages rather than streaming or browsing.
All Ultra Mobile plans are month-to-month. You can change your plan or cancel at any time without paying an early termination fee. This is different from some carriers that lock you into a contract for one or two years.
How much Ultra Mobile costs compared to other carriers
Ultra Mobile's prices change frequently, so you should check their website for current rates. Generally, Ultra Mobile's monthly plans cost less than T-Mobile's standard plans for the same amount of data, because Ultra Mobile has lower overhead costs. However, Ultra Mobile is not always the cheapest option — other MVNOs on T-Mobile's network, like Mint Mobile or Metro by T-Mobile, may offer lower prices in some months.
The real cost difference depends on how much data you use. If you use very little data, a pay-as-you-go plan from Ultra Mobile might be cheaper than a monthly plan. If you use a lot of data, you may find a better deal with a carrier that offers unlimited data plans, even if the monthly cost is higher.
Ultra Mobile does not charge set up fees or require you to buy a phone. You can bring your own phone and start service when ready, which saves money compared to carriers that charge setup fees.
How to switch to Ultra Mobile or add it as a second line
If you want to switch from another carrier to Ultra Mobile, you will need your phone number ported over. Ultra Mobile can handle this during signup — you provide your current carrier's account number and PIN, and Ultra Mobile requests the port on your behalf. The process usually takes a few hours to a few days. During the port, your old service will stop and your new Ultra Mobile service will start.
If you want to keep your current carrier and add Ultra Mobile as a second line, you can buy a new phone number from Ultra Mobile instead of porting. This is useful if you want to test Ultra Mobile's service before switching completely, or if you need a separate number for work or travel.
You can sign up for Ultra Mobile online through their website or by calling their customer service line. You will need a valid payment method (credit card or debit card) and a compatible phone. If you are bringing your own phone, make sure it is unlocked before you start the signup process.
What happens if you run out of data or minutes
If you have a monthly plan and you use all your data before the month ends, Ultra Mobile will not automatically charge you extra. Instead, your data speeds will slow to a very slow rate (usually 2G speeds), and you can still send texts and make calls if your plan includes unlimited talk and text. You can purchase additional data for the rest of the month if you need faster speeds again.
If you have a pay-as-you-go plan, you will be charged per megabyte once you run out of your prepaid balance. You can add money to your account at any time through Ultra Mobile's website or app.
Ultra Mobile sends notifications when you are approaching your data limit, so you have a chance to add more data or switch to a different plan before you run out.
International use and roaming with Ultra Mobile
Ultra Mobile's standard monthly plans do not include international data or calling. If you travel outside the United States and use your phone, you will be charged roaming rates, which can be very expensive — sometimes several dollars per megabyte of data.
Ultra Mobile offers separate international plans that include data and calling in specific countries or regions. These plans are cheaper than standard roaming if you travel regularly. You can add an international plan to your account before you travel, or you can purchase a separate international plan just for the trip.
If you travel to a country not covered by Ultra Mobile's international plans, you can still use your phone on local networks, but you will pay roaming rates. Before you travel, check Ultra Mobile's website to see which countries are covered and what the rates are.
Frequently Asked Questions
Can I keep my phone number if I switch to Ultra Mobile?
Yes. During signup, you can request that Ultra Mobile port your number from your current carrier. This process usually takes a few hours to a few days. You will need your current carrier's account number and PIN to start the port.
What happens if Ultra Mobile's service is bad in my area?
Ultra Mobile uses T-Mobile's network, so the coverage is the same as T-Mobile's. If T-Mobile has weak signal in your area, Ultra Mobile will too. You can check T-Mobile's coverage map on their website before you switch to see if service is reliable where you live and work.
Do I need to sign a contract with Ultra Mobile?
No. All Ultra Mobile plans are month-to-month, and you can cancel or change your plan at any time without paying an early termination fee. This is one of Ultra Mobile's main advantages over carriers that require contracts.
Can I use Ultra Mobile if I have bad credit?
Yes. Ultra Mobile does not run a credit check and does not require a deposit. You can sign up as long as you have a valid payment method and a compatible phone. This makes Ultra Mobile an option for people who have been denied service by other carriers.
What if I want to switch back to T-Mobile or another carrier later?
You can switch at any time. Request that your phone number be ported to your new carrier, and your Ultra Mobile service will end. There are no penalties or fees for leaving Ultra Mobile.
