SimTether Keeps Your Home SIM in the Loop

Editorial interest 84/100 Selection signal · not a rating of the site

An iPhone app that relays SMS messages from a SIM left in an Android phone at home, including replies sent from the original number.

Landing page captured for the 2026-08-24 issue.

Field notes

The proposed setup uses an old Android as a relay handset rather than moving the number or involving a carrier. Incoming messages are pushed to the iPhone, and replies return through the original SIM as ordinary SMS, with carrier charges applying only to those replies. SimTether says its archive stays on the user’s phone and messages are deleted after delivery, while acknowledging that SMS is exposed on the mobile network before reaching the home device.
