NEW YORK (AP) -- Twitter is buying the Indian mobile marketing company ZipDial as it tries to reach new users in developing regions.
The San Francisco company did not disclose financial details or when it expects the deal to close.
ZipDial connects tech companies with consumers in emerging markets where mobile data is expensive and Wi-Fi connections are limited. With ZipDial, consumers bypass data charges. They call a unique phone number, hang up and then receive free texts or voicemails with sports scores, coupons or other content and information.
Calling and hanging up is also a way to follow users of Twitter Inc. A phone number can be assigned to politician, for example, and users receive tweets through texts instead of going to Twitter's website.
