If you have a stiff and complex technical problem the staff in the Herceg Novi shop (a) do not speak sufficient English to understand your queries and (b) are not technically competent enough to deal with your problem.

After buying a Tourist SIM card from them for 2 weeks use, and inserting it into a MIFI device [wireless router] it didn't work for data transactions. Why? because they hadn't given me the correct APN and telephone number to sign on to use. Their Website had no information regarding this and their staff were technically incompetent.

Many years ago Montenegro's mobile telephone companies were far more technically competent and gave you the full information you needed to operate your equipment. This is no longer true of Telekom.me who are totally incompetent.

for 4 G devices the log on APN username is tmcg-4g password 38267

On top of my APN issue was the SMS number and text code to use for how much data I had left and when did my connection die? The staff in the shop showed no understanding what my enquiry was about. No comprehension of English, the international language used across Europe. Telekom.me's website was useless for my type of enquiries. Other websites like FANDOM's didn't have up to date information.

I'll not be using telekom.me tourist SIM card services again.

In addition they have an automated ticket queuing system. It also was bust, not a good advert for their services.
