AT&T hidden fees and billing traps in Switzerland
The primary AT&T billing trap in Switzerland is involuntary activation. Any network activity triggers the full $12 charge. This includes background email syncs, push notifications, iMessage delivery confirmations, and automatic app updates. A single iMessage that falls back to SMS while your phone searches for a data connection counts as network activity and triggers Day Pass. Without Day Pass enrollment, AT&T defaults to pay-per-use at $2.05 per megabyte. Half a gigabyte of unintended background usage generates over $1,000 in charges. AT&T caps Day Pass at $120/month after 10 days, but this cap does not apply to pay-per-use charges.
