Customer Reviews
Good deal, quick delivery
Ordered a Nintendo Switch Bundle last week and was pleasantly surprised. The discount activated automatically when I chose my tariff, which saved me about 50 Euros without needing a special code. Versand took only a few days, so that was excellent.
Good deal, easy process
I got an iPhone mit Vertrag a few weeks ago, the o2 Mobile M plan. The ordering was straightforward on their website, no confusing steps. Delivery took about 4 days, which felt reasonable enough. Setting it up was simple. The phone quality is obviously excellent, and the network coverage in my area (Berlin) has been solid so far. Haven't needed customer support, so can't comment there. Overall, a smooth experience.
New tablet, decent experience
Needed a new tablet for work and grabbed an iPad mit Vertrag. It was pretty easy to order online. The shipping was alright, took maybe 5 days to get here. No issues setting it up. It works fine, everything as expected. Happy with it.
Great value on the plan
I was really looking for the best deal on a new phone plan and ended up with the o2 Mobile L. I qualified for the Junge Leute Rabatt, which saved me 10 Euros monthly right off the bat. That was a big factor in my decision. I also got a small hardware discount on my Samsung Galaxy with Vertrag. Compared to other providers I checked, this felt like the best bang for my buck. Totally worth it for the savings.

Hey, thinking about grabbing a new iPhone with a plan. How long does shipping usually take to like, Berlin?
Does o2 do that young people discount for apprentices too, or just students?
