Is there a good free iOS app that can replace my phone plan?

TextNow is a prominent choice for users seeking a no-cost alternative to a traditional cellular plan. The core offering is a free, dedicated phone number for calls and texts within the United States and Canada, operating entirely over a WiFi connection. This makes it particularly suitable for individuals looking to minimize expenses, such as students, those with limited cellular coverage at home, or anyone needing a separate business or temporary number. A significant feature is the cross-platform accessibility, allowing messages and calls to sync between an iPhone, iPad, and a desktop computer, which is beneficial for users who switch devices frequently.

However, the model has trade-offs. To remain free, the service is ad-supported within the app. While call and text functionality is robust for general use, some user reviews indicate occasional inconsistencies with audio quality during calls. A notable limitation for certain use cases is that receiving SMS verification codes from banks or other services typically requires a low-cost monthly 'Premium' subscription. For basic, ad-supported communication, TextNow delivers reliable service, but those dependent on two-factor authentication texts will need to factor in the small extra cost.
