Ultra Mobile questions, answered
What Ultra Mobile costs, which towers it uses, how much data you get and whether eSIM works — written from the 2 live plans we track for this operator.
We may earn a commission if you buy through links on this page. It never changes how we rank plans, and every price is checked against the operator’s own listing.
How many Ultra Mobile plans can I compare here?
We currently track 2 live Ultra Mobile plans, priced from $10 to $20 per line each month. Each one is listed on the Ultra Mobile page with its own price, data allowance and link to the operator.
Which network does Ultra Mobile use?
Ultra Mobile is operated by T-Mobile US and its service runs on T-Mobile. That means the towers you connect to are the host network's towers, so signal in your area follows that network rather than Ultra Mobile building its own masts. 2 of the plans we list include 5G access.
How good is Ultra Mobile coverage where I live?
Coverage depends on the T-Mobile footprint at your address, not on Ultra Mobile itself. Use our coverage checker to enter your ZIP and see the filed figures for that network, plus the registered structures nearby. Where a network has not filed data with the FCC we say "not filed yet" rather than estimating it.
What is the cheapest Ultra Mobile plan?
The lowest monthly price we currently track is $10 per line with autopay. Prices move often, so the figure on the operator page is always the one we checked most recently.
How much data do Ultra Mobile plans include?
Capped plans go up to 25 GB of high-speed data. Once a capped allowance is used, speeds are reduced for the rest of the billing month rather than data being cut off.
Does Ultra Mobile support eSIM?
Yes. Ultra Mobile supports eSIM, so a compatible phone can be activated by scanning a code instead of waiting for a physical SIM. 2 of the plans we list are flagged as eSIM ready. Check that your handset is unlocked and eSIM capable before you buy.
Are there activation fees or contracts?
The Ultra Mobile plans we list are month to month, with no fixed term. We have not recorded an activation fee on the plans currently listed.
Can I keep my phone and my number?
In most cases yes. A phone bought unlocked, or unlocked by your previous operator, will work as long as it supports the T-Mobile bands. Your number is kept by requesting a port from Ultra Mobile during signup — do not cancel your old service first, or the number can be lost.
How current are these Ultra Mobile prices?
The most recent check on this operator's listings was Sep 9, 2026. We re-check prices against the operator's own page and only publish what we can see there.
Do you make money if I switch to Ultra Mobile?
Sometimes. If you buy through a link on this site we may earn a commission from the operator or its affiliate network. It never changes the ranking, the prices we show, or which plans appear — those come from the same verified catalogue either way.
