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.
Quo
- Unlimited calling to US and Canadian numbers is subject to a Fair Usage Policy rather than being truly unlimited
- Starter tier's $15/user annual rate requires prepaying annually; monthly billing costs $19/user, about 27% more
- The Sona AI agent automation credits are capped at 1,000 free per plan before additional usage is billed
