Costs, limitations, and important caveats
The use of call forwarding can be free or have a cost depending on your rate and operator. Some key points:
- Activating call forwarding is usually free; What's charged is the redirected call. The caller pays up to your number, and you pay the part from your number to the final destination.
- In contracts with flat rate calls or minute bundles, the cost may be included.
- For prepaid plans or plans without unlimited calls, the cost depends on the plan.
- Calls cannot be diverted to international, short-circuit or special service numbers. (803, 806, 807, 905, 118xx, etc.).
- Some operators limit the number of call forwarding options or limit compatibility with other services such as call control, multi-conference calling, or call barring.
- Activation/deactivation does not affect SMS messages.
Remember that proper management of your deviation can help you save costs and avoid surprises on your bill.
Alternatives, tips and common solutions
Although call forwarding is the easiest way to manage the reception of multiple lines, there are alternatives and tricks If you need more flexibility:
- Advanced management apps: Some apps (such as Truecaller or business phone apps) allow you to set more complex rules for call forwarding, scheduling, contact filters, etc.
- Simultaneous call: In business environments, simultaneous reception can be configured on multiple devices (softphones, mobile phones, computers) so you don't miss any calls.
- Internal portability: If you have multiple physical SIM numbers, consider using Dual SIM or eSIM phones to manage multiple lines from the same phone without having to forward. (Forwarding is still useful if you travel or turn off a line entirely.)
- Forward to voicemail: If you don't want to miss calls but don't want to answer them on another number, you can redirect them to your voicemail.
- If you're working remotely or traveling, activate call forwarding before you lose coverage to ensure all calls reach your preferred destination.
Remember that SMS forwarding does not affect calls; only calls are redirected.
