Sometimes a website (e.g. Amazon) will ask for a mobile phone number so they can send you a text message (e.g. to track a shipment), but they also ask you which carrier you use (e.g. AT&T, Verizon, etc.).
If I want to give them my Google Voice number, which carrier should I specify?
As an example, Amazon provides the following options:
- Cellular South
- Cincinnati Bell
- Midwest Wireless
- Nextel Communications
- Sprint PCS
- US Cellular
- Verizon Wireless
- Virgin Mobile
Note that you must choose one, this is not an optional field. If someone could explain why websites such as these even need your carrier information, that would help as well.
