＋メッセージ（プラスメッセージ）

Rich messaging apps combine SMS simplicity with email's versatility — and ＋メッセージ（プラスメッセージ）delivers exactly that. This messaging solution from a major Japanese carrier lets you send photos, videos, stamps, and text using only a phone number — no registration required. Connect instantly with friends, family, and businesses using just your contacts list.

Start messaging immediately without sign-up friction. Your app syncs seamlessly with your device's contacts, so anyone you know is ready to message. When someone not in your contacts reaches out, their message displays as "Not registered" — keeping you aware and safe. Group messaging supports up to 100 people at once, turning quick chats into lively multi-person conversations. Share rich media including photos and videos up to 100MB each, plus maps and contact information, giving you far more expression than traditional SMS.

Stamps bring personality to every exchange. Download your favorite designs from the free stamp store and use them to add emotion and flair to conversations — something plain text simply cannot match. The read receipt feature lets you know when someone has opened your message, though you can disable notifications if you prefer privacy. Text messages support up to 2,730 full-width characters, perfect for longer thoughts that don't need email formality.

Experience secure communication with verified business accounts. Official company accounts display a carrier-verified mark, so you can confidently receive notices, complete procedures, and submit inquiries without worry. Whether you need customer support, service updates, or business transactions, official accounts are clearly identified and trustworthy.

Audio files, map sharing, and contact exchange round out a complete communication toolkit. Your profile stays private, visible only to people you message or add to contacts. All stamps download for free, so expression never costs extra. The invitation feature helps you spread the word to friends still using older messaging apps.

Choose ＋メッセージ（プラスメッセージ）to upgrade beyond basic texting without the complexity of traditional messaging apps — instant, safe, and fun for everyone.
