Coverage. Telekom owns the most extensive network in Germany, especially in rural and alpine areas. O2 brands like ALDI TALK are fine in cities but drop signal faster outside them. If you regularly travel to small towns, ski resorts, or wine regions, D-Netz is worth a euro or two extra per month.
Same network, different speed caps and price. congstar caps at 25 Mbit/s on prepaid; Telekom-branded prepaid goes up to 300 Mbit/s. For most users (web, social, video at HD), 25 Mbit/s is more than enough. congstar saves you €5-10/4w.
fraenk bundles Switzerland in roaming and is monthly billed (not 4-week). Annualised, fraenk at €120/year is cheaper than NORMA at €116.87, basically the same. The 50 cents/year you save on NORMA vanishes the first time you take your phone to Zurich and pay zone-1 roaming.
Yes. Telekom, congstar, fraenk, NORMA, KAUFLAND, ja! mobil, and Penny Mobil all use the same Telekom cell sites. Signal quality is identical. The differences are in speed caps, customer service language, and retail channel.
