Call Forwarding details
- You cannot forward to international numbers.
- You can only forward calls to 10- or 11-digit numbers.
- Forwarding while roaming depends on the host country's network capabilities. If the capability exists, you are charged international roaming plus applicable long distance.
Call Forwarding Conditional (CFC)
- Allows you to forward your voice, fax, and data calls to another number based on certain conditions.
- If busy (no available route for incoming call; may occur if a call arrives while dialing out)
- If no reply (call is not answered for up to 30 seconds)
- If not reachable (device is turned off or out of signal range; data device with wireless mode is off)
- Once the condition is met and the call is forwarded, you have a bucket of 500 CFC minutes. Once the 500 minute bucket is exceeded any additional minutes will incur overage. It will not deduct from a rate plan bucket.
- "If Unavailable" is a combination of the three conditions above, most devices automatically forward voice calls to voicemail under the "If Unavailable" condition. Voicemail forwarding does not use the CFC bucket.
- Calls forwarded to another T-Mobile number bill as T-Mobile to T-Mobile instead of deducting from the 500 CFC bucket.
Call Forwarding Unconditional (CFU)
- Allows you to unconditionally (always) forward voice, fax, and/or data calls to another phone number.
- Unconditionally means that the system immediately sends calls to the designated phone number.
- Usage deducts from the applicable bucket depending on when the call was forwarded.
- If CFU is set to route calls to voicemail or another number while roaming, you won't be charged if the phone is off.
- This is because you have Unconditional Call Forwarding set up and the call will be redirected to voicemail or the other number and never delivered to your handset.
- However, if your phone is turned on while roaming and a Voicemail MWI is delivered, then you will be charged for the delivery of the MWI.
