The starting position
The first difference lies in the network: Post Mobile transmits on the Salt network (around 99 % of the population), Swisscom on the Swisscom network (its own network) (99.8 % of the population). Anyone who travels a lot or lives in an outlying region should therefore check the coverage at their own location first and only then look at the price.
The second difference is positioning. Post Mobile: low prices plus personal advice in-store. Swisscom: network coverage, service and premium included features.
It's also a duel of two business models. Swisscom sells network plus service — Switzerland's largest store and service network. Post Mobile mainly sells the price — online and in every post office branch.
At the entry price, there's CHF 47.95 per month between the two — over a contract term of 24 months, that's a CHF 1150.80 difference, in favour of Post Mobile.

Network and coverage
Post Mobile: Salt operates its own network with around 99 % 4G population coverage; 5G rollout is concentrated on cities and agglomerations. In some regions, coverage is weaker than with Swisscom — it's worth checking the coverage map for your place of residence.
Swisscom: The Swisscom network is considered Switzerland's reference network: 99.8 % population coverage, leading in 5G rollout, and a regular test winner at Connect and CHIP — even in mountain and remote regions.
On paper, the Swisscom network leads in population coverage. In everyday use, the difference is small for most users; it becomes noticeable in remote regions, indoors, and under high network load. More on this in the Network comparison Switzerland.
Switching from Post Mobile to Swisscom — and vice versa
The number stays with you in both directions: you request the port from the new provider, who handles the switch with the old one. The order matters — first the check the cancellation and its notice period, then submit the porting request, so the number is not switched off beforehand. Details are in the article on Number portability.
If all you want is a lower price, you do not necessarily have to switch: sometimes a call to your current provider is enough. When switching is worth it anyway is explained in Switch instead of renewing.
Conclusion: Post Mobile or Swisscom?
On today’s data the winner is Post Mobile with 7 to 4 of 14 points. What weighs more heavily: low prices plus personal advice in the store. Entry there costs CHF 11.95 per month, 6 plans are available to choose from, unlimited data from CHF 11.95.
What speaks against Post Mobile: small range, no large roaming packages. That's exactly where Swisscom is strong: network coverage, service and premium included services — from CHF 59.90 per month. Anyone who weighs one of these arguments more heavily than the overall score is right to choose Swisscom; the table above shows line by line where the difference lies.
And if neither of the two fits: in the Overall comparison all Swiss providers stand side by side, with the same daily prices.

How this head-to-head is produced
Alle Zahlen auf dieser Seite kommen aus unserer Tarifdatenbank. Die Tarife werden jede Nacht automatisch von den offiziellen Anbieter-Websites eingelesen; die Angaben geben den Stand vom 6. Oktober 2026 wieder und werden bei jeder Aktualisierung neu berechnet — inklusive Kategoriesieger und Punktestand.
12 criteria worth up to 15 points are available for scoring; in this head-to-head, 11 criteria worth 14 points were sound. Criteria for which a provider states no comparable figures — such as EU roaming without a stated gigabyte amount — are left out of the scoring and marked in the table. Network, entry price and the cheapest plan with unlimited data count double, all other criteria once. Prices count as equivalent if they are less than CHF 1.00 apart, shares up to 5 percentage points of difference; such rows end in a draw. For the network we assess only the stated population coverage — the Sunrise and Salt networks therefore count as equivalent for us, while the Swisscom network leads with 99.8 %.
The top scorer is calculated purely from the criteria above. handy·abo is an offer from MARKTIX AG and is financed through referral commissions. With equivalent offers — almost identical price and scope — we name partner providers first. Where the text speaks of “the cheapest” plan, the genuinely cheapest is always meant, irrespective of any partnership. Details in the Affiliate disclosure.
