Pros and cons

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

PremiumSIM

Pros

  • Sim only plans start at €6.99, below the €9.30 median across listed brands
  • Terms run 1 and 24, so a rolling option sits next to a longer commitment
  • 5G, eSIM and wifi calling are all available, which is what most listed mobile plans carry

Cons

  • The fibre line carries a setup fee of €49.99 and post contract pricing of €44.99
  • As an mvno, the provider sets its own tariffs on another carrier's network and stays inside DE
  • Uploads of 5.8 to 40 Mbps sit below downloads of 1,000 Mbps, which matters for sending large files

Who each suits

MobileX

Who it suits

  • Residents of US who want a prepaid plan with no long contract
  • People who want unlimited talk and text from $14.88
  • Readers who want an eSIM, rollover data and hotspot sharing on a flexible plan

Who should look elsewhere

  • GETESA readers who would rather buy from a network than a mvno
  • Lonestar Cell MTN readers who want the network itself rather than a virtual brand
  • Travellers who need roaming inside the monthly plan, since European roaming is paid

PremiumSIM

Who it suits

  • People in Germany who want a sim only plan on 1 and 24 terms
  • Households that want mobile and a fibre line from one seller, with €49.99 to budget for at the start
  • Travellers who need EU roaming included in 33 countries

Who should look elsewhere

  • Anyone after unlimited data, since no unlimited plan appears among the reference plan prices
  • Buyers who want the host network itself, where yesss! sells as a network
  • People who need service beyond DE, with Lonestar Cell MTN listed as a network

Questions about each

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.

PremiumSIM

What does the cheapest PremiumSIM mobile plan cost?+

The starting price across the range is €6.99, set on a small allnet plan. A second reference plan adds a much larger data allowance at a higher monthly cost, and no unlimited plan appears among the reference plan prices. Heavy data users would pay for the larger tier from the first bill.

How long is the contract?+

Plan contract months run 1 and 24, so a short rolling arrangement sits alongside a longer commitment. Billing is offered as contract or rolling, which lets you match the term to how long you expect to keep the line. Households that expect to move soon should read the longer term carefully.
