Summary
To switch to Sidephone from an Android smartphone: disable RCS, complete Sidephone’s Setup Wizard, move your SIM / mobile plan (or choose a new private number), and configure the keypads around your core needs (calls, texts, navigation).
If you rely heavily on Google and RCS, and are not willing to abandon these services, you can keep your Android as a quiet companion device and use tools like LocalSend and Beeper to keep both devices in sync.
Steps
Make Sidephone your primary and only device (recommended)
Make Sidephone your primary and only device (recommended)
Complete the steps below to retire your Android smartphone, and set up Sidephone as your primary and only mobile device:
Prepare your Android
This is a critical first step in order to ensure text message deliverability.
On your Android, open Messages → ⋮ → Settings → Chats (RCS) and turn RCS off
Restart your Android phone
(If you no longer have your Android) disable RCS via Google’s “Disable Chat” page in a browser
Set up Sidephone for the first time
Follow steps in: Set up Sidephone for the first time
Move your number to Sidephone
Power off your Android and move your SIM into Sidephone (if using a compatible carrier)
eSIM: If your existing plan is eSIM, it may be simpler to adopt Sidephone's mobile service using the provided SIM card as opposed to purchasing and waiting for your existing carrier to mail a new one, which may or may not be supported
Place a test call and send a test SMS to confirm standard texting works
Tip: Do not discard the Sidephone SIM card or its contents. If connectivity fails to initialize with your existing carrier, or if you prefer to experience connectivity that the team has tested to work best with the device, Sidephone mobile plans are available to activate with the provided SIM card.
Embrace Sidephone's minimalism and de-Googled OS
Use Sidephone primarily for calls, SMS, navigation, and light utilities
Install essential apps from the App Library (e.g., Maps if you need it) or other trusted sources
If using Compact QWERTY, install JakeType first
Open Settings → Key Mapping and map hotkeys to quick launch apps like:
Phone
Messages
Contacts
(Optional) Maps
Accept that you will no longer have native Google Backup, Google Photos, or RCS and instead explore privacy-focused platform agnostic solutions like Proton, Cryptee and others
Keep your existing Android device as a quiet companion
Keep your existing Android device as a quiet companion
We recommend keeping your long-standing number on your existing device, and seeing Sidephone as a new fresh start with a new private number.
Set up Sidephone for the first time
Follow steps in: Set up Sidephone for the first time
Power off the device to prepare for the next step
Obtain your new private number
Visit plans.sidephone.com and choose either a Basic ($10/mo) or Unlimited ($35/mo) plan
Enter your newly activated SIM card into Sidephone
Power on Sidephone
Tip: Choose an unlimited plan for your new private number on Sidephone and call the provider of your existing long-standing number to reduce that plan to call/text/1GB or just call/text. Since the Android smartphone will mostly stay at home, with access to a Wi-Fi network, it might no longer need a more expensive plan.

Use your Android smartphone only when Sidephone cannot do the task, or you have time boxed the use for work that is only available on the smartphone
Install advanced utilities to bridge the gap between devices
Install tools like Beeper from a trusted source, which will allow you to access all incoming RCS texts on your prior Android device and send them just as if you were on your old smartphone
The goal of these additional tools should not be to replicate your old smartphone, but to make Sidephone more usable so that you can more confidently choose it to be your new daily driver and primary mobile device.
Considerations
Some contacts can text you, others can’t: Fully disable RCS through Google's web form at https://messages.google.com/disable-chat
Data-only SIM: Calls/SMS won’t work; confirm your plan supports voice and SMS
Google-dependent apps and services: Many won’t run on Sidephone by design; plan around this
Large photo transfers fail: Send in smaller batches via LocalSend
No Wi-Fi available: Create a hotspot on your Android and connect Sidephone to it for transfers
You miss RCS: Use the 'Android as a quiet companion' setup and consider Beeper as a bridge
When to Contact Support
Create a support ticket if:
you cannot receive standard SMS on Sidephone after disabling RCS and restarting, or
calls/texts fail on a confirmed working SIM
What to Collect for Support
Was RCS turned off in Android Messages (or via Google’s site)?
Did you move your main SIM to Sidephone or use a new number?
Can you receive a standard SMS on Sidephone?
Are you attempting a companion-device setup?
