I strongly warn against Lyca Mobile! Service in Switzerland keeps ignoring all complaints despite that they failed totally and STOLE my money: I have bought a card with 50 GB internet plan during my travel to Switzerland. I clearly explained my needs to Lyca Mobile representative in the shop. He gave me a Lyca Mobile leaflet with promo activation, I had to buy a Lyca SIM card and initial top up. Then I was to use the leaflet to top up more via internet and later activate my package. It did not work for 2 days, so I called Lyca support, talked over one hour and finally the representative told me they would refund my top up, as I had been mislead by sales representative. I was informed that the promo was available only for transfer from other operator, but it was mentioned in German on the leaflet so I was not able to understand, so I trusted Lyca representative. I agreed to refund my funds and waited patiently. After a week I asked again by email for the refund. So asked 10 times and they or answered with generic answer or finally stopped answering, did not refund money. So I was traveling through Switzerland without service, without internet and lost my money and couple of hours talking and mailing to Lyca support. Never buy Lyca Mobile, as if you have any issues they will not help and they will steal your money!
