despite three attempts - no functioning Map

After contact with the seller, I have received a new card immediately.

2. Map:
inserted card has registered on the network and I could 1x phone. Phone off - After a few days turned back - message: SIM card registration failed ... tried to call the number of the SIM card: "The number you have dialed is not assigned"

Seller sent a third card.

3.Karte:
inserted, "registration card has failed" If you call belonging to the SIM mobile phone number, you get the message: "The number you have dialed is not assigned"

Communication with the seller very good, also a replacement delivery - but ultimately I now still no functioning card ....

However, the communication was flawless with the seller and I quickly get my money back.
