Spent an hour and a half buying a local SIM card. Not an Indian-style ordeal (though even in India these days you can avoid such hassle), but it took forever.

There was a SIM card shop right across from where I was staying. It seemed logical to buy there. The seller honestly tried to follow all the rules and submit my data to the regulatory authority (that's the law). Except the internet on the regulator's end wasn't cooperating.

After the fifth attempt to submit the application (each taking about 15 minutes), I gave up and went looking for another shop. Just around the corner, in 10 minutes they sold me a SIM registered to a local person (technically not allowed, but apparently if you really want it, you can make it happen). Why didn't I just go there in the first place?

PS. The connection is mediocre: sometimes the signal just disappears. A couple years ago the local regulator even fined all the major operators for terrible service quality. They say it's gotten better :)
