Understanding the Swiss telecom market

Moving to Switzerland means getting to grips with a number of new systems, from healthcare and housing to banking and telecommunications. The Swiss telecom market may seem unfamiliar at first, particularly if you are used to a different system in your home country. However, it is based on a few simple principles.

In this guide, find out how mobile plans work in Switzerland, what types of internet connection are available, what to consider when choosing a provider, and what newcomers should know before signing up.

How do mobile plans work in Switzerland?

Switzerland has three companies that operate their own mobile networks: Swisscom, Sunrise and Salt.

Alongside these three network operators, there are many other brands that use one of these networks and offer their own mobile plans. What matters is which network the provider uses and what is included in the plan.

There are two main types of mobile plans in Switzerland:

Prepaid

With a prepaid plan, you add credit in advance and use it as needed. There is no long-term contract, which can make this a convenient option when you have just arrived in Switzerland.

Prepaid plans can also be useful if you do not yet have a Swiss residential address or simply want a temporary solution while you settle in. However, the cost per gigabyte is generally higher than with a contract plan.

Postpaid or contract plans

With a postpaid plan, you pay a monthly fee for the services included in your contract. Plans often come with a minimum commitment of 12 or 24 months.

Compared with prepaid offers, postpaid plans generally provide more data and may include benefits such as EU roaming. They can, however, require a Swiss residential address and, in some cases, a credit check.

Postpaid plans have become the most common option in Switzerland, with contract customers representing the majority of subscribers across the country's three major networks.

Identity verification for every SIM card

If you are buying a Swiss SIM card, there is an important requirement to be aware of.

Since 2023, Swiss law requires identity verification for all SIM cards, whether prepaid or postpaid. You will therefore need to provide a valid passport or identity card. Depending on how you purchase your SIM card, this may be done in a store or digitally for an online order.

How much do mobile plans cost?

The Swiss telecom market is highly competitive, which has helped make mobile plans more affordable than you might expect given Switzerland's generally high cost of living.

Different providers compete on price, data allowances, roaming and additional services. Salt, in particular, has positioned itself as a value-focused provider, offering competitive prices while operating its own national mobile network.

When comparing your first Swiss mobile plan with what you paid in your home country, it is worth looking at several providers and considering both the monthly price and what is included in the plan.

Fibre, 5G or DSL: understanding internet options in Switzerland

When choosing home internet in Switzerland, the most important factor is often not the provider but the technology available at your address.

There are three main types of connection to consider:

Fibre (FTTH)

Fibre to the home is generally the fastest and most stable type of fixed internet connection available. Depending on the plan and infrastructure, it can provide multi-gigabit speeds.

Fibre coverage has expanded significantly in Swiss cities and larger towns. However, availability can still vary from one building to another, particularly in older properties and rural areas.

DSL / VDSL

DSL and VDSL connections use the existing copper telephone network and remain available in many buildings, particularly older ones.

They are generally sufficient for everyday activities such as browsing, streaming and video calls. However, they offer lower speeds than fibre, and performance can depend on the distance between your home and the local network infrastructure.

5G home internet

5G home internet provides a third option. Instead of using a fixed cable or fibre connection, a 5G router connects your home to the mobile network.

This can be particularly useful if you are living in temporary accommodation, need an internet connection quickly or live somewhere where fibre is not yet available. Performance will depend on the quality of 5G coverage at your address.

Salt offers high-speed options at both ends of the telecom market. Its Salt Home fibre plans offer speeds of up to 10 Gbit/s, while its mobile network has also performed strongly in independent network testing.

Always check availability at your specific address before choosing an internet provider. The same provider may offer fibre at one building but only DSL or 5G at another nearby address.

Most major providers, including Salt, offer an online address checker. Checking your address first will help you compare plans that are actually available to you.

What should newcomers know about Swiss telecom services?

The Swiss telecom market can seem expensive when compared with other European countries. However, competition between providers has increased significantly over the past decade, giving consumers more choice and putting pressure on prices.

For newcomers, the main challenge is often understanding what is actually included in a plan. Mobile data allowances, EU roaming, contract length, network coverage and installation requirements can all vary between offers.

Frequently asked questions

Which companies operate mobile networks in Switzerland?

There are three main network operators: Swisscom, Sunrise and Salt. Many other brands use one of these networks to offer their own mobile plans.

Can I get a prepaid SIM card in Switzerland?

Yes. Prepaid plans are available and can be a practical option when you have just arrived, particularly if you do not yet have a Swiss residential address.

Do I need to verify my identity to get a Swiss SIM card?

Yes. Identity verification is required for all Swiss SIM cards, whether prepaid or postpaid.

Is fibre internet available everywhere in Switzerland?

No. Fibre availability depends on the specific address. It is therefore important to check your building before choosing a fibre plan.

Is 5G home internet a good alternative to fibre?

It can be. 5G home internet can be particularly convenient for temporary accommodation or locations where fibre is not available. Its performance depends on local 5G coverage.

In summary

The Swiss telecommunications market may seem different from what you are used to, but the main principles are straightforward.

For mobile services, you can choose between prepaid and postpaid plans, with the three main network operators being Swisscom, Sunrise and Salt. For home internet, the options available to you will depend largely on your address and the network infrastructure in your building.

Where Salt stands out is at the fast end of this spectrum on both fronts. Salt Home fibre plans reach speeds up to 10 Gbit/s — among the fastest available anywhere in the country — while its mobile network has been recognized in 2025 nPerf testing for leading fixed and mobile network performance nationally, including download speed, upload speed, and latency.

Taking the time to compare the available options will help you find a plan that suits your needs and avoid paying for services you do not require.

For newcomers, checking network and service availability at your address, understanding the contract terms and comparing what is included in each plan are the most important steps before signing up.
