I need some advice regarding mobile plans in Bulgaria.
I subscribed a plan in a Vivacom store. (the plan you can see on this link to be more specific http://nixanbal.com/vivacom-puska-neogranicheni-minuti-kam-vsichki-i-16-000-mv-4g-internet-za-23-99-lv).
First of all, it struck me that I had to pay a special deposit of 115 Leva as I'm a foreigner... But I did. The sim card worked well (4G everywhere, etc). A couple of weeks later, it stopped working (impossible to place a call, send SMS or data), I went to the store, and I was told that I had placed International calls (which was true but for a reasonable amount, ~10min of Europe outgoing calls) and I had to pay an extra deposit of 20 Leva. I tried to get more details, and I learned that they needed a larger deposit for calls not included in the plan. I paid again and it started working again.
The straw that broke the camel back is the roaming. I'm now traveling in Europe (Hungary and Slovakia) for a couple of weeks, and I can't get the Vivacom sim card to work when my other sim cards from other countries work nicely. Everytime I try to call, a message says that I'm not authorized to make a call. The message is in Slovak, so I suppose that the call is not routed to Vivacom infrastructure which made me suppose they didn't have roaming agreement (or roaming service included).
Questions : Did you guys have to pay deposit ? Are you happy with Vivacom ? Should I terminate that contract and see if the grass is greener with another operator ? The thing is that to stop the contract it will cost me 3 months of penalty.
