What's New in SIMPlus

4.5.6

June 23, 2026

SIMPlus update: accounts made easier, connections made tougher This release focuses on two things you’ll actually feel: smoother account management, and more reliable reconnections. - We redesigned the account experience — settings, email binding, password updates, and account deletion are clearer and easier to follow. Login and registration now validate as you type, so small mistakes get caught early instead of after you tap “Submit.” - Managing multiple accounts? History is easier to browse and switching is faster — less digging, more doing. - On the call side, we improved recovery after background incoming-call wake-ups and network changes, so the app gets back online more reliably when life (or your router) interrupts. Update SIMPlus and enjoy a version that’s a little smarter, a little steadier, and a lot less frustrating.
