Unlimited mobile internet in Switzerland: plans, prepaid and costs
Unlimited mobile internet is worthwhile if you often stream on the go, use a hotspot or do not want to keep checking your usage. But it is not essential: a small data allowance may be enough if your phone is usually on Wi-Fi. Compare the extra cost of services you actually need rather than relying on a fixed GB threshold.
As of 1 November 2026. The selection below is based on official tariffs, not our own speed tests. It covers different usage profiles and does not claim to offer the lowest price across the entire Swiss market.
Specific plans for Swiss data and travel
Plan | Base price | Switzerland / abroad |
Digital Republic Flat Mobile One | CHF 13 / 30 days | Unlimited data, calls and SMS in Switzerland; 3 GB and 30 minutes in the EU/USA according to the country zone. |
Digital Republic Flat Mobile Two | CHF 18 / 30 days | Unlimited domestic services; 20 GB and 100 minutes in the EU/USA according to the country zone. |
Galaxus Mobile CH Unlimited | CHF 19 / month | Unlimited Swiss data, calls and SMS; 3 GB in the EU/USA. |
Galaxus Mobile International | CHF 29 / month | Unlimited Swiss services; EU/USA data with 20 GB at full speed and 100 minutes of EU/USA calls. |

Comparing costs properly: 30 days is not a month
Our calculation assumes unchanged prices and excludes devices or extra usage: Galaxus CH Unlimited costs CHF 228 for twelve full months and CHF 456 for 24 months. International costs CHF 348 and CHF 696 respectively. Group and student discounts are not included here. This makes these standard prices easier to compare with an individual contract.
Twelve 30-day Digital Republic One packages cost CHF 156 but cover only 360 days. For uninterrupted coverage over 365 days, this payment model requires 13 packages: CHF 169 for a total of 390 days of coverage. For 730 days, you need 25 packages: CHF 325 for 750 days. This is the amount paid for whole packages, not a usage price calculated to the exact calendar period. The separately offered annual version costs CHF 143 for 365 days and commits your advance payment for longer. Tariffs and durations
Both providers list CHF 0 activation for the mobile plans compared here: Digital Republic One and Galaxus tariff list. Additional SIMs, international calls or special numbers may still incur costs. An advertised flat rate does not remove the need to check these items.
Which unlimited plan suits which profile?
Lots of data, little travel: shortlist One and CH Unlimited if reception and the respective contract terms suit you. Larger international packages do not automatically add value to everyday life in Switzerland. Avoid paying for the most expensive package all year for an occasional holiday month without calculating the alternative of individual travel packages.
Regular travel: also compare Two and International. The amount of high-speed roaming data, included calling destinations and speed after the allowance runs out matter more than the word “unlimited”. Reduced speed can be impractical for video conferences even when a data connection remains available.
A hotspot for work: at your usual workplace, test an actual video call and file upload as well as running a speed test. A good download result alone does not prove that the connection is stable. Also read the rules on personal use, routers and network management. We are not claiming that every mobile plan is an equivalent replacement for a fixed broadband connection.
Is unlimited data available on prepaid too?
Yes. The blanket claim that Swiss prepaid stops at 10–15 GB is incorrect. Sunrise Unlimited CH offers unlimited domestic services for CHF 2.50 per 24 hours of use. Swisscom Flat 30 offers unlimited Swiss data at up to 50 Mbit/s and domestic calls for CHF 65 over 30 days. “Unlimited” and the maximum available speed are therefore separate features.
Prepaid can make sense for short periods of intensive use. For everyday use, however, compare usage costs over the entire period. Cancellation is a separate point to check: a plan without a long minimum term may still have a notice period. When switching with number porting, do not terminate the old contract independently of the porting request.
Compare unlimited mobile plans by usage and roaming needs (in German). Then compare the total amount payable and the earliest confirmed exit date.
