AT&T hidden fees and billing traps in United Kingdom

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.
