Why are People Seeking an Alternative to Line2?
People are mostly searching for Line2 alternatives because of unreliable customer service, frequent technical difficulties, problems with billing, and a lack of advanced features.
Poor Customer Service
Many long-time users have felt neglected by Line2's support team. Its reviews have mentioned delayed responses, lack of follow-up, and a frustrating support experience. Customers have reported issues like being unable to reset passwords or access accounts, with no clear path to resolve the problem. Even after 15 years with the platform, some users stated they felt ignored and forced to consider switching.
Billing Issues
Users have also reported billing issues, such as being charged for canceled lines and facing long delays in getting refunds. These surprise charges and poor support make people lose trust and look for other options.
Technical Issues
Technical instability appears to be another major concern. Users have cited problems like texts not going through and the app logging them out unexpectedly. Several reviewers also noted that the app did not run reliably in the background, leading to poor call quality and frequent disconnections. Inconsistent performance is a dealbreaker, especially for those using Line2 for work.
Lack of Advanced Features
Line2 offers only a basic set of VoIP (Voice over Internet Protocol) features like voicemail, caller ID, and call forwarding, among others. However, today’s users expect more, such as AI-powered call reports, CRM integration, IVR (Interactive Voice Response) systems, sentiment analysis, or even simultaneous ring. This makes the platform outdated compared to more advanced competitors.
