AT&T, Verizon, Sprint, T-Mobile etc. If you want to text somebody else, you'll have to figure out their carrier first though. :(
Is their a way determine their carrier without asking?
- runn1ng 14y agoMost of US-based do. No such luck in here (Czech).
- ComputerGuru 14y agoMost VoIP providers have a "number lookup" feature. For example, here is my number looked up on CallWithUs: http://cl.ly/image/1l1g071h1d0C http://cl.ly/image/1l1g071h1d0C You can create an unfunded account with them and use the lookup feature, if I'm not mistaken. (Though I don't recommend doing so, it's not nice!)
- pudquick 14y agoThe central register for area code + prefix is here: http://www.nanpa.com/reports/reports_cocodes_assign.html http://www.nanpa.com/reports/reports_cocodes_assign.html However, sometimes the companies listed are subsidiaries and you can't tell the 'major' cellular provider for someone at a particular number.
- amatix 14y agoIn the US, does number portability between networks exist? In NZ, it causes problems with SMS gateways, which seem to (in general) naively use the prefix as the sole means of identifying which operator for a number.
