2G and 3G switch-off in Bulgaria
Quick answer
2G in Bulgaria: No dates announced. Bulgaria's 3G phase-out is under way but slower than elsewhere: A1 began switching off regions in early 2025, Yettel aims to be ready to switch off 3G by 2027, and Vivacom has set no date. All three say 2G will stay on for M2M devices.
