Carrier vs. eSIM
Mobile carriers push you into long-term commitments, bundled plans, monthly statements. eSIM skips all that — you buy exactly what you need.
Traditional B2B contract
Contract
12–24 month commitment on company ID with early-termination penalties.
Invoice
Monthly, paper or data-mailbox, often 14–30 days after the period ends.
Price predictability
Bundle + roaming + FUP overage + extras = surprise total.
Plan changes
Paper request, negotiation, often with a change fee.
Roaming and travel
Roaming bundle with FUP, often missing non-EU countries.
Data-only, no contract
Contract
No commitment. Stop by not topping up — no notice period.
Invoice
PDF by email instantly after payment. Books today, not next month.
Price predictability
Final price is the price. What you buy is what you pay.
Plan changes
Online checkout — buy a different plan whenever, no negotiation.
Roaming and travel
Per-country destination eSIM. Outside EU without roaming shock.
