Expect strong signal in cities, along motorways and on main rail corridors. Remote regions, deep tunnels and some mountain passes may drop briefly to 3G or no signal — this is the same behaviour any local SIM would show.

- Vivacom — 4G/5G, primary carrier in Plovdiv and surrounding regions
Bulgaria eSIM vs UK roaming: real cost in £
Answer: Save up to 90% vs UK roaming. Most travellers spend £4–£15 on a TripSIM Bulgaria plan instead of £40–£250 on UK roaming for the same trip. The reason is simple — UK carriers charge £5–£8 per MB once you leave EU roaming zones, and Bulgaria is outside most UK "roam-like-at-home" bundles. A 5 GB TripSIM Bulgaria plan replaces what would otherwise be £5–£8 per MB × thousands of MB.
- Quick check-in trip (3 days, ~3 GB): TripSIM ~£4–£8 vs UK roaming ~£60+
- Standard holiday (7 days, ~10 GB): TripSIM ~£8–£15 vs UK roaming ~£150+
- Long trip / digital nomad (14+ days, unlimited): TripSIM single fixed price vs uncapped roaming charges
- Heavy maps + video calls user: still capped at the TripSIM plan price — no bill shock

Bulgaria eSIM frequently asked questions
Will my UK phone work with a Bulgaria eSIM?
Yes — if your phone is eSIM-compatible (any iPhone XS or newer, Google Pixel 4+, Samsung Galaxy S20+ and most 2020-onward Android flagships) and network-unlocked. Phones bought outright from Apple, Google or the Samsung UK store are unlocked by default. Contract handsets from EE, Vodafone, Three or O2 are unlocked automatically as well.
How quickly is the Bulgaria eSIM delivered?
Activation details land in your inbox within a few minutes of paying. We recommend installing the eSIM at home on UK WiFi before you fly, then activating it when you land in Sofia.
Can I keep my UK number while using a TripSIM Bulgaria eSIM?
Yes. Modern phones run two SIM profiles at once. Keep your UK SIM as the default voice/SMS line for bank verifications and use the TripSIM eSIM as your data line. WhatsApp, iMessage and your normal apps keep working on your UK number.
Does the TripSIM Bulgaria eSIM include calls or texts?
TripSIM is a data-only eSIM — no traditional voice minutes or SMS, and no emergency-call routing through this line. Use WhatsApp, FaceTime, Google Voice or Microsoft Teams for calls. Keep your UK SIM active for SMS one-time codes and 999/112 emergency dialling.
