I’ve read several of the Skip Langdon series from the first one through maybe the 5 one, and I like the Skip Langdon character but the Talba character has become more silly and irritating IMHO with each book.
I got this one before; yes, they send you a SIM, but they also send you the card. I tossed the SIM and used the card on my phone. Added an easy year for next to nothing.
