Our verdict

Yoin is a Belgian sim only brand that suits light data users and households wanting several lines on one bill, with plans starting at €6.50 a month on a term of 1 month. The catch is travel: EU roaming is fair use, so frequent use abroad sits outside the bundle.

Pros and cons

Pros

  • Plans start at €6.50 a month, with two larger data bundles above the entry plan and monthly billing on every tier.
  • Nothing is locked in: billing is rolling with a plan contract of 1 month.
  • eSIM, the newest generation of mobile data and a multi line discount all come with the range rather than as extras.
  • Support runs on email, phone and chat, so help is reachable by phone, chat, email or the help centre.
  • Plans run on Proximus, so coverage comes from an established host operator.

Cons

  • EU roaming is fair use, so the bundle is not built for heavy streaming abroad.
  • Plans are sold in BE only, which puts the brand out of scope for anyone who needs service in another market.
  • Rolling billing on a 1 month term means you reprice every month, so a cheaper rival can undercut you quickly.
  • As an mvno, Yoin sits a step away from the host network, so support and plan changes run through the brand rather than the network.

Who it suits

  • Light and moderate data users in BE who want a sim only plan and a monthly bill they can end quickly.
  • Households adding a second or third line, since a multi line discount is available.
  • Buyers who want to activate on eSIM and keep the newest mobile generation at a low monthly cost.

Who should look elsewhere

  • Readers who want the host network's own plans instead of an mvno bundle can compare GETESA, listed as a network.
  • Anyone needing plans outside BE has no option here, and a network seller such as yesss!, listed as a network, is a different route.
  • Frequent travellers who expect generous roaming, since EU roaming here is fair use and Lonestar Cell MTN, a network, carries its own terms.

Core features

Yoin sells sim only plans, so no handset is folded into the monthly cost. The range runs on Proximus and is billed on rolling terms, with a plan contract of 1 month. Entry pricing starts at €6.50 a month, and two larger monthly data bundles sit above it for heavier use, so the monthly figure is what you pay rather than a promotional opening rate that changes later. Every plan includes the newest generation of mobile data, so nobody is pushed onto an older network generation, and eSIM is supported, which means a line can be set up digitally instead of waiting for a card in the post. A multi line discount is available, so a household paying for several numbers can bring them onto one bill and bring the cost per line down. Between them these cover what most buyers in BE look for in a cheap monthly plan. Travelling is the detail to read closely: EU roaming is fair use, so the bundle works abroad under fair-use conditions rather than on unlimited roaming, and heavy data use abroad is where that qualifier bites. Because the contract length is 1 month, a cheaper offer elsewhere can be picked up as soon as a month ends, with no long notice period to serve.

The company behind it

Yoin is run by Yoin NV, based in Belgium and trading since 2021. It is an mvno, so the plan is sold, billed and supported by Yoin while the network underneath comes from the host operator. Questions about a number, a bill or a plan change therefore go to Yoin rather than to the host network directly. The company operates in a single market: BE is the only market listed, so anyone who expects a second country to be covered should settle that before signing up. Customer service runs on email, phone and chat, which means a phone call, a live chat, an email or the help centre are all ways in, and the help centre is the place to check the fair-use terms before ordering. With trading starting in 2021, Yoin is a younger operator than the network it buys capacity from. The practical test for a new brand is simple: whether the monthly figure, the 1 month term and the fair use roaming terms match the way a household actually uses its data.

Frequently asked questions

What does the smallest Yoin plan cost each month?+

Plans start at €6.50 a month. Above that sit two larger monthly data bundles for heavier users, and every tier is billed monthly, so the monthly figure is the standing cost rather than an introductory rate. The entry bundle is aimed at light data use.

Is there a contract to tie me in, and what happens at renewal?+

Billing is rolling and the plan term is 1 month. There is no long contract and no opening rate that later steps up; a plan can end when the month ends, and since you reprice every month, a cheaper rival can undercut you quickly.

Which network does Yoin run on, and where is it sold?+

Yoin is an mvno selling on Proximus, so coverage and speeds follow that host network. Plans are marketed in BE only, which means the brand is not a fit for anyone who needs service in a second market.

Do the plans include the newest mobile generation and eSIM?+

Both are listed as included. The plans run on the Proximus network's newest generation where it is deployed, and eSIM support means a line can be provisioned digitally rather than posted out as a physical card.

What happens to my data when I travel in the EU?+

EU roaming on Yoin plans is fair use, not unlimited. Occasional trips are fine inside the bundle, but heavy data use abroad can run into fair-use limits, so frequent travellers should read those terms before committing to a plan.

Can I get a discount on several lines?+

A multi line discount is listed, and that is the main argument for putting extra numbers on one Yoin bill. Combined with entry pricing of €6.50 a month and a term of 1 month, a family can add lines without a long commitment.

How do I reach Yoin support?+

Support runs on email, phone and chat, so a phone call, a live chat, an email or the help centre are all available. The help centre is the quickest place to confirm fair-use roaming terms before a plan is ordered.

How long has Yoin been trading, and who runs it?+

Yoin has been trading since 2021 and is registered as Yoin NV with its base in Belgium. As an mvno on Proximus, it is a newer outfit than the network it sells capacity from.
