Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Line
- Line has negligible market share outside Japan, Taiwan and Thailand, so it is the wrong choice for reaching contacts in most other regions.
- A 2021 incident exposed that some user data had been accessible from servers operated in China, which led to a formal restructuring of data governance and remains a reference point for privacy sensitive users.
- Standard chats are not end to end encrypted by default in the way Signal is; Letter Sealing, an opt-in encryption feature, has to be manually enabled per chat.
- Business messaging through Official Accounts becomes expensive quickly once a company exceeds the free monthly message allowance and moves to a metered plan.
- Ownership sits inside a SoftBank and Naver joint venture with a history of governance disputes between the two partners, which creates strategic uncertainty for enterprise customers relying on the platform long term.
Vonage
- MMS pricing not published publicly, requires sales team quote
- International SMS rates can exceed $1.00 per message in some markets
- Smaller developer ecosystem compared to Twilio
