Our verdict

Swisscom suits Swiss households that want the SIM, the network and the roaming handled by a single company, and the blue Mobile S entry plan starts at CHF 39.90 a month. The trade-off is term length: plans run 24 months, so anyone who expects to move or switch pays for stability with flexibility.

Pros and cons

Pros

  • Entry and unlimited pricing meet: blue Mobile S starts at CHF 39.90 a month and the unlimited plan is listed at CHF 39.90, so unlimited data costs nothing extra.
  • Sim only, 5G and an eSIM are all offered, so a handset already in your pocket and an extra device can sit on the same bill.
  • A multi line discount applies, which lowers what each additional number costs on a household bill.
  • Support covers chat, phone and help centre, so help is available by phone as well as online.

Cons

  • Plans run 24 months, a long tie-in for anyone who might move home or change provider.
  • Roaming in the EU runs on fair use terms, so heavy use abroad is limited rather than open ended.
  • yesss! bills on contract, rolling and prepaid, which includes a rolling option that the contract and prepaid setup here does not list.
  • Swisscom serves a single market, CH, so anyone based elsewhere needs a different provider for these plans.

Who it suits

  • Swiss households that want the SIM, the network and the support desk handled by a single company.
  • Families running more than one line who can put the multi line discount to use.
  • Travellers whose European use stays light enough for fair use roaming terms.

Who should look elsewhere

  • yesss! for anyone who wants a rolling monthly option, since its billing is listed as contract, rolling and prepaid.
  • Lonestar Cell MTN for shoppers who decide on the entry figure alone, since its price from is listed at $0.20.

Plans and prices

Swisscom is a network seller, so the monthly figure comes from the host network rather than a reseller. The blue Mobile S entry plan starts at CHF 39.90 a month, and the unlimited plan is listed at CHF 39.90 a month. The two numbers match, which matters when weighing entry against renewal: the cost of unlimited data is the same as the cheapest way in, so a household starting at the bottom of the range is not pushed onto a higher bill for a bigger allowance. Tiers above the entry point, such as blue Mobile XL, cost more each month, so CHF 39.90 is the floor for a Swisscom bill and the figure to hold in a budget.

Core features

Four items define how these plans work day to day. Sim only is offered, so a phone already in your pocket can go on a plan without a new handset. 5G is available, which matters for recent phones and for busy places. An eSIM is supported, so an extra line for a tablet or watch can be activated and moved without a card being posted out. A multi line discount applies, so a household with several numbers pays less per line than a single line would. Together they make Swisscom a practical fit for people who would rather the SIM, the network and the family plan sit with a single company.

How it compares on our data

The site ranks brands on two measures, and Swisscom's place on them is worth reading together. On price from it sits at 257 of 258 brands, and on unlimited price at 155 of 173. Both figures put it well down the field rather than near the cheapest end, so a Swisscom bill should be expected to cost more than the entry offers on the site. The unlimited ranking lands ahead of the entry ranking, which is the useful detail: the tier most households actually pick compares more favourably than the headline starting price does. Readers on a tighter budget should weigh that tier, not the entry figure, against cheaper plans.

Frequently asked questions

How much does the cheapest Swisscom plan cost?+

The blue Mobile S entry plan starts at CHF 39.90 a month. The unlimited plan is listed at CHF 39.90 a month, so the entry figure and the unlimited figure sit at the same level. That makes the cheapest way in also the cheapest route to unlimited data, while higher tiers such as blue Mobile XL cost more each month.

How long is the commitment on a Swisscom plan?+

Plans run 24 months, which is a long tie-in on a mobile bill. Billing is offered as contract and prepaid, so a prepaid option sits alongside the contract and can be used without a long term. Readers who expect to move or change provider should weigh the length before the monthly figure.

Can I use Swisscom with a phone I already own?+

Sim only is offered, so a handset brought from elsewhere can be used on these plans. 5G is available on the network for compatible phones, and an eSIM means no card has to be posted out. Billing runs on contract and prepaid terms, so a sim only line can sit on either a contract or a prepaid setup.

Does Swisscom offer an eSIM and 5G?+

Both are supported. An eSIM can be activated and moved between devices without a physical card, and 5G is available on the network. Plans are sold by the network itself, so the SIM and the service come from the same company, and support is handled on chat, phone and help centre.

Is there a discount for more than one line?+

A multi line discount applies, so each extra number on the same bill is cheaper than a line bought alone. Billing runs on contract and prepaid terms, which means several lines can share an invoice rather than needing separate billing. Sim only plans also make it simple to add a tablet or watch to the same account.

What happens to data when I travel in Europe?+

Roaming in the EU runs on fair use terms, so use abroad follows fair use rules instead of a fixed allowance on the plan. Travellers who stream or use data heavily on a trip should read those fair use terms before committing to a contract, since the usual monthly figure does not extend to unlimited roaming.

How do I get help from Swisscom?+

Support runs on chat, phone and help centre, so help is offered by phone and by chat alongside a help centre and a community board. Phone support matters for account changes and roaming problems, where a written answer takes longer to act on. Anyone planning a switch should also keep the contract term in view when opening a case.

Where does Swisscom sell its plans, and how does it price?+

Swisscom serves a single market, CH, and sells as a network rather than a reseller, so plans and network come from the same company. On the site it is placed at 257 of 258 brands on price from, and at 155 of 173 on unlimited price.
