No. Annual packs run for 12 months from purchase, then expire. Your number stays active but data, calls, and SMS revert to PAYG rates after expiry. Buy a new pack before the year ends to avoid surprise per-MB charges.
Different data sizes. O2's 150 GB pack at €89.99 is mid-tier; ALDI TALK's 60 GB at €69.99 is entry-level. On price per GB, supermarket packs at the same size as O2 are equivalent or slightly more expensive. O2 wins absolute price below 150 GB; supermarket brands win below 60 GB.
Annualised cost is usually lower. A €8.99 4-week tariff at 25 GB = €116.87/year for 325 GB total data. O2 Jahrespaket = €89.99/year for 150 GB. Per GB the 4-week tariff is cheaper, but if 150 GB is enough, O2 saves €26.88. Pick annual when you know your usage stays steady; pick 4-week when you might need flexibility.
1&1 sells monthly contracts, not annual prepaid packs. The closest 1&1 product is the All-Net-Flat 10 GB at €14.99/mo ongoing (=€179.88/year for 120 GB). Worse value than annual prepaid on Telekom or O2.
