The Prepaid Plus from Swisscom is actually only interesting if you also have a Swisscom landline internet subscription, because only then will you get the first 500 MB with higher speed for free with the Plus.
For infrequent users with mobile data consumption set to minimal, this 500 MB/month is actually enough.
If you don’t have a Swisscom landline Internet subscription for the Prepaid Plus “gift-carrying” plan, but you do have a dual-SIM capable cell phone, then you’re better off buying a 0.4 flat rate from Digital Republic or just for the mobile data from Galaxus, and are at least three times faster than Swisscom at a slightly lower price of CHF 4/month.
If this isn’t enough, then simply try the next higher bit rate for CHF 10/month for a month, which will certainly be enough for every standard mobile need.
