Staff is rude. They talk to friends ignoring people that are waiting in line. They offer only expensive plans. Just check plans and prices on their website before your visit.
We issued a SIM card very quickly, and immediately offered the function of saving the number. Diana served us, she speaks Russian well and helped her colleagues along the way. One of the few places where the service is very fast.
If you come to Batumi, then take care of a good connection. The first time I took a SIM card at some stall, which I seriously regretted later. The second time I decided not to make a mistake and issued a SIM card at the central office. The service is excellent, all operators speak Russian
