Pros and cons
Pros
- Price from of €0 places yesss! at rank 1 of 258 brands on price from, and SIMpure adds pay-per-use usage with no commitment.
- Sold by A1 Telekom Austria AG as a network seller, so the tariff, the SIM and the A1 coverage come from one company.
- Billing covers contract, rolling and prepaid, so you can pay as you go or commit to a yearly rate.
- Support runs on email, chat and phone, so help is not tied to a single channel.
- Both 5G and an eSIM sit on SIM only plans, so a recent handset can be used from day one without buying a new phone.
Cons
- EU roaming is fair use rather than included, so trips with heavy data use abroad sit under fair use rules.
- Contract terms run 1 and 12 months, so the SIMple M yearly price locks you into a term, while the rolling and prepaid options in contract, rolling and prepaid do not.
Who it suits
- People in Austria who want the lowest way onto the A1 host network, since price from is €0 and SIMpure has no base charge.
- Anyone who wants to avoid a long tie-in, because billing includes rolling and prepaid options alongside contract and SIMpure is pay-per-use with no commitment.
- Recent handsets that want 5G and an eSIM on a SIM only tariff, without buying a new phone to go with it.
Who should look elsewhere
- Frequent EU travellers who expect roaming included, because EU roaming here is fair use; GETESA, which bills on prepaid and contract, is a different arrangement to check.
- People chasing unlimited data, since the reference plan prices stop at SIMple XL 5G, so a wider comparison such as Astound makes more sense.
- Buyers who want a different host network: yesss! runs on A1, while Lonestar Cell MTN bills on contract and prepaid and may suit another pattern.
What it does well
Everything yesss! sells is SIM only, so you bring your own handset and keep whichever number you already have. That suits anyone who has just finished paying off a phone, or who likes the handset already in their pocket and would rather not stretch the bill to cover new hardware. The service is 5G, so a recent phone connects to the faster network where it is available. An eSIM is offered as well, which removes the wait for a card in the post and turns activating or changing a plan into something done on screen. SIM only plus an eSIM plus 5G adds up to a plan that can be started, changed and carried around quickly, and none of it ties you to buying a phone. What you give up is the handset, the in-store advice and any hardware discount that would come with buying the phone on the same bill.
Who runs it
yesss! is sold by A1 Telekom Austria AG and is based in Austria. It is a network seller rather than a shopfront, and that shape decides who answers when something goes wrong: the company you pay is the company running the service, so the tariff, the SIM and the coverage all trace back to one operator. Support runs on email, chat and phone, so a question can go by email, chat or phone with a help centre alongside, rather than through a single inbox that forwards everything elsewhere. If a bill looks wrong, or coverage at a particular address disappoints, you raise it with the operator that runs the network. For a buyer, knowing exactly who stands behind the tariff matters as much as the number on the advert.

Frequently asked questions
What does it cost to get started with yesss!?+
The entry price is €0, and SIMpure is pay-per-use with no commitment, so there is no base monthly charge to start from. If you want a bigger allowance on a fixed term, SIMple M yearly is the budget option, and SIMple XL 5G is the largest listed bundle.
What happens to the price when the term ends?+
The published SIMple M yearly figure is the price for a year-long plan, and contract terms run 1 and 12 months, so check what you want at renewal rather than assuming the same rate carries over. SIMpure sidesteps the question: it is pay-per-use with no commitment, so you pay for what you use in each month.
Is yesss! the network itself or a reseller?+
It is a network seller, and the service runs on the A1 host network, so the company taking your money is the company operating the network. An eSIM is offered too, which means a compatible handset can be set up without a card arriving in the post.
What about roaming across the EU?+
EU roaming is fair use, so data used abroad sits under fair use rules rather than an included allowance. If you travel for long stretches each year, or stream while away, treat roaming as a cost to plan for rather than something the monthly price already covers.
Do I have to sign up for a fixed term?+
Not necessarily. Billing runs on contract, rolling and prepaid, so a prepaid option, a rolling monthly option and a contract option all exist. SIMpure is pay-per-use with no commitment at all, while the SIMple M yearly price is tied to a term of 1 and 12 months.
Who do I contact if something goes wrong?+
Support runs on email, chat and phone, so email, chat, phone and a help centre are all available, and yesss! is sold by A1 Telekom Austria AG. A coverage query, a billing question or an eSIM swap goes to the operator running the network rather than being passed along to someone else.
Is there an unlimited plan here?+
Not on the list. The reference plan prices top out at SIMple XL 5G for data, and SIMpure starts at €0 with pay-per-use usage and no base charge, so heavy use simply shows up on the bill. If unlimited matters more than a low starting point, a broader comparison is the better route.
Where does the service work?+
The service is sold by A1 Telekom Austria AG, which is based in Austria, and the plans sit on the A1 host network. Use in Austria is what the tariff is built for; elsewhere in the EU, roaming is fair use, so regular travel abroad is limited by fair use.
