Our verdict on each
MasMovil
MasMovil is a Spanish network selling its own SIM only lines with no minimum term, which suits readers who want a short commitment and a low entry price of €4.90. The trade-off is a narrow feature list: data does not roll over and calls over wifi are out.
MobileX
MobileX suits US readers who want a prepaid plan with a low entry price and no contract attached, scoring 9.4 overall. Build Your Own starts at $3.88 on 1 month, and that same monthly rate carries into every later period, so nothing has to be unwound at renewal.

Pros and cons
MasMovil
Pros
- Entry price of €4.90 sits below the site median of €9.30, and it ranks 87 of 258 brands on that measure.
- Plan terms run 1 month, so there is nothing to serve out before you leave.
- Sim only tariffs are available, and eSIM is offered, so you can bring a light line without a handset.
Cons
- Data rollover is not available, so unused data is lost at the end of each cycle.
- Lonestar Cell MTN lists an entry price of $0.20, lower than €4.90, so the cheapest way in sits with that brand instead.
- Roaming in the EU runs on fair use terms rather than being included outright.
MobileX
Pros
- Build Your Own starts at $3.88 on a plan where the data allowance is set by the customer
- Plans run 1 month, so there is no long term to serve
- Unlimited talk and text plans start at $14.88
Cons
- European roaming is paid, so travel adds cost rather than arriving with the plan
- The seller type is mvno, so service runs over a host network and local coverage needs checking
- Coverage is listed for US, so anyone who needs service across several countries should look wider
Who each suits
MasMovil
Who it suits

- People who want a SIM only line and a term of 1 month with no long commitment.

MobileX
Who it suits
- Residents of US who want a prepaid plan with no long contract

Questions about each
MasMovil
How much does a MasMovil line cost to start?+
Lines start at €4.90, which is below the site median entry price of €9.30. Across the site, €6.99 is the typical starting figure for this kind of deal, and €6.99 is the typical figure among mobile networks.
Do I have to sign a long contract?+
Plan terms run 1 month, so there is no long minimum to serve. That is a good match for anyone who expects their data use or income to change and wants to leave without a large exit bill.
MobileX
What is the cheapest MobileX plan?+
Build Your Own starts at $3.88 and you set the data allowance on it yourself. The published reference prices for the plans are monthly and month to month, so that entry figure is the ongoing figure rather than a promotional rate that changes later. A reader comparing a low headline price with a long contract deal is comparing two different structures here, not two stages of one sale.
Does MobileX use contracts or lock-ins?+
No long term is attached. Billing is prepaid and rolling and plans sit at 1 month, the short contract length that flexible mobile deals tend to use. Nothing ties you in for a year, so a reader who wants to change plan or walk away can do so without serving out a term first.
