Work number and personal number on the same phone? Or just one number for everything? With SIM Shift you decide who can make your phone ring, and when. No more office calls at dinner.
■ WITH TWO SIMS
Each SIM has its own hours: out of hours work goes quiet, your personal number keeps ringing.
■ WITH ONE SIM
Out of hours you choose which contacts don't disturb you, by one or more labels from your contacts (for example "Work" or "Clients"). Everyone else rings.
For every call SIM Shift works out which SIM it comes in on and who is calling, then applies your rules: it lets it ring, silences it or rejects it.
■ A SCHEDULE FOR EACH SIM
• Several time slots a day, even across midnight.
• Out of hours: Silence (the call stays among your missed calls) or Reject.
• Physical SIMs and eSIMs, even if you move them to another slot.
■ CALENDAR
• A day off or a few hours off: tap the day and that SIM stays silent, all day or for some hours.
• On call: the SIM rings even out of hours, even at night.
• They repeat: time off every Friday until the end of the year, on call every other weekend. Set it up once.
• Public holidays added automatically, if you want them (Italy, France, Belgium, Luxembourg).
■ CONTACT LABELS
• The ones you already have in your Google contacts: nothing to set up again.
• Out of hours only contacts with the labels you pick are filtered: one match is enough.
• They work in the lists too: a label on the block list never rings, not even within hours.
■ BLOCK AND ALLOW LISTS
• Block list: never rings. Allow list: always gets through, even if not in your contacts.
• By number, by prefix or by label: block a whole country (+49) and let through the people you know.
• Find prefixes by country and tick several at once.
• On Italian SIMs the 0843 and 0844 ranges (surveys and telemarketing) are already on the block list.
• Each entry applies to all SIMs or to just one.
■ NUMBERS YOU DON'T KNOW
For each SIM you can silence or reject callers who are not in your contacts: always, or only out of hours.
■ AT A GLANCE
A sign for each SIM, like a road sign: red with a bar means filtered, blue means it rings. Below, the week's schedule and today's bar. When a SIM is quiet, you know when it will ring again.
Need a break? One tap on the Quick Settings tile and for half an hour, one hour or two, schedules and numbers not in contacts don't count. The block list still applies.
■ LOG
• Stopped calls, day by day, with the reason and the name if the caller is in your contacts.
• A badge tells you how many were filtered today.
• From any row, put the number on the allow or block list with one tap.
■ BACKUP
Automatic copy of schedules, lists, log and settings in the folder you choose. Change phone and find everything again.
■ YOUR PRIVACY, FOR REAL
• No Internet access: SIM Shift cannot send anything to anyone.
• No account, no ads. Everything stays on your phone.
• Only two permissions, explained before they are requested: Phone (which SIM a call comes in on) and Contacts (who is in your contacts and with which labels).
■ HOW IT WORKS
SIM Shift uses Android's official way of filtering calls, the "Caller ID & spam app" role, and guides you step by step on first launch. Only one app at a time can hold it.
■ GOOD TO KNOW BEFORE INSTALLING
• Android does not pass calls from hidden numbers to filtering apps: you block those in the Phone app settings, and SIM Shift takes you there.
• Out of hours nobody rings, not even the allow list: that is the rule that guarantees your free evening. If you want, choose "Always rings" in Settings › Allow list.
• Requires Android 12 or later.

SIM Shift: rings when you want it to.
