Before starting a call with two SIMs, check three things separately: who you are calling, which outgoing line you will use and the retry settings. A correct destination number does not confirm your outgoing line. Knowing which SIM supplies mobile data is not enough either.
AutoRedial’s published facts list dual-SIM support. This guide proposes a pre-call check using an invented case; it does not reproduce a screen or promise the same selector on every phone.
The contact is the same; the chosen line may differ
Imagine two lines you have identified as “Personal” and “Work”. You want to call someone with whom you have agreed to use Work. You have found the right contact, but have not checked which line is selected.
The decision at this point is not to shorten the retry interval. Identify the available line and choose the appropriate one first. If you cannot distinguish them confidently, leave the session unstarted while consulting your device settings and documentation. You need not make a test call to someone else to resolve an unfamiliar label.
A check before starting
| Item | What to check in the fictional case | What it does not establish |
|---|---|---|
| Destination | This is the intended contact | That Work is already selected |
| Outgoing line | You have identified and selected Work | That the call will connect |
| Retry settings | You reviewed waiting time, interval, maximum and conditions | That any attempt count is appropriate |
This is a manual proposal, not three new AutoRedial fields. It supplies no real numbers and assumes no call result. If the phone offers only one usable line, do not infer that the application can create or activate another.
Data settings do not answer the whole question
Google documents separate Pixel preferences for calls, messages and data. Samsung also explains choosing a SIM for each use. These are manufacturer instructions, not a description of AutoRedial’s buttons.
Consult the guide for your model and version. Do not copy a Pixel settings path expecting an identical menu on another phone. Support depends on the device, SIM, carrier and capabilities exposed by Android; two cards on a table do not establish that both lines can make calls.
Separate line selection from session settings
After identifying the line, review the destination and session settings before starting. AutoRedial’s product sheet lists answer wait, interval, maximum attempts and conditions for busy, unanswered or disconnected calls. We offer no universal values and do not claim a shorter wait will get an earlier answer.
Our case’s preparation is complete when you know the selected contact and line and have reviewed those settings. You have not yet called or confirmed a conversation. For costs, credit, restrictions or line identification, consult your carrier; this guide does not certify those conditions.
Keep control when the plan changes
The product sheet lets you stop a session, including from its notification. It also documents the cycle stopping on connection, at the attempt limit or on an error. Stopping retries and hanging up a conversation are different actions: AutoRedial never automatically hangs up an active call.
If you no longer need to call, do not leave the decision unresolved just because you configured a session. Review its state and stop it when appropriate. We claim no automatic SIM switching within a session, line alternation or guaranteed connection.
Check the product and phone before buying
AutoRedial is a paid app for Android 10 or later and requires the default-phone role. Its cycles run locally and exclude emergency numbers. Read its capabilities and limits and follow the official Google Play link from its website to check current availability and compatibility.
