[Xoxzo] SMS Character Limit Expanded to 660!

According to the GSM specification, a single SMS in Japanese is limited to 70 characters. But what if you need to send more? With Xoxzo’s SMS API, you can now send messages up to 660 characters long — all from a mobile number, and at a lower cost than traditional direct mail.
