Network and coverage
Salt and Post Mobile use the same network. Salt operates its own network with around 99 % 4G population coverage; 5G expansion is focused on cities and agglomerations. In some regions, coverage is weaker than Swisscom's — it's worth checking the coverage map for your location.
For the choice, this means: reception, speed and coverage are identical. Anyone switching from one of the two plans to the other won't notice any difference in the network — only on the bill. What it actually looks like at your address is shown by the Coverage check.
Switching from Salt to Post Mobile — 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: Salt or Post Mobile?
On today’s data the winner is Salt with 5 to 5 out of 14 points after a tie-breaker. What tips the scales: promotional prices on unlimited plans and the large plan selection. Entry there costs CHF 13.95 per month, 13 plans are available, unlimited data from CHF 13.95.
The case against Salt: the best prices are usually tied to a 24-month contract term. That's exactly where Post Mobile excels: low prices plus personal advice in-store — from CHF 11.95 per month. Anyone who weighs one of these arguments higher than the overall score is right to choose Post Mobile; the table above shows row by row 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 %.
This duel ends in a tie. In this situation, we name the editorially higher-prioritised provider first. 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.
