Example with specific numbers
Example: Tariff comparison - 300 min calls, 100 SMS, 5 GB internet
- Monthly usage:
- Calls: 300 minutes
- SMS: 100 messages
- Internet: 5 GB
- Tariff A: Base 20 BGN + additional services = ~35 BGN/month
- Tariff B: Everyday tariff 25 BGN = ~30 BGN/month
- Tariff C: Unlimited tariff 40 BGN = 40 BGN/month
- Most beneficial: Tariff B (30 BGN/month)
For usage of 300 minutes calls, 100 SMS, and 5 GB internet, Tariff B is most beneficial at 30 BGN/month. Tariff A requires additional payments and costs 35 BGN, while unlimited Tariff C is expensive (40 BGN) for this usage. The comparison helps you choose the optimal tariff according to your needs.
