When looking for this information, most sites are vague & strongly advise eSims. I will use an eSim, but my husband has an older phone that is incompatible so needs an actual Sim. Our plan was to go directly from Munich airport to the first town on our itinerary using the Deutschland ticket which needs to be displayed when requested by the conductor. With no data he won't be able to do that. The obvious solution (to us) would be to buy a Telekom Sim at the airport, but everything I've read stresses that this will cost a) slightly more or b) 2 to 3 times as much as at a city outlet, and offers less choice. Last time we purchased at the Telekom store in Munich there was limited choice as well, offering only a Magenta Mobile "L" instead of the "M" which he wanted.
If you have done this, was it twice as much? Three times? Only slightly? Only offering the more expensive "L" or equivalent? Or is it possible to display both tickets on one phone and I am totally overthinking this?
Any information gladly accepted. Thanks in advance.
