SilentSIMs / DEVICE FIELD MANUAL
A practical dual-SIM setup checklist for iPhone and Pixel
Check model support, carrier lock, line labels and mobile-data preferences before configuring a separate SIM on an iPhone or Google Pixel.
Check the exact device and regional variant first. Then confirm carrier support, label each line and deliberately choose which SIM handles mobile data, calls and messages.
What dual SIM actually changes
Dual SIM gives a compatible phone more than one mobile connection. That can be useful for separating personal and work use, or choosing a different line for mobile data. It does not create a separate operating system or isolate every app automatically. Start by deciding what you want the additional line to do. That purpose determines which defaults you should inspect.
Check the model, not just the product family
Support varies across device generations, regional variants and carriers. Do not assume every phone with the same family name accepts the same combination of cards and profiles. Read the model details in Settings, check the manufacturer’s documentation and confirm support with the intended service. The links below go to current manufacturer instructions rather than a copied model list that may become stale.
For iPhone: pay attention to the data line
Apple documents several supported dual-SIM combinations and notes that iPhone uses one mobile-data network at a time. Using two different providers also requires an unlocked iPhone, unless both plans come from the same provider. After adding a supported line, check the labels and the connection selected for data. Review switching options so the resulting behavior matches your intent.
For Pixel: support depends on the device and carrier
Google’s guide distinguishes the supported combinations of physical SIM and eSIM, and notes carrier and regional exceptions. It also explains separate preferences for calling, messaging and data. Use the guide for your exact device and installed software. If an expected option is missing, verify support before deleting profiles or repeating an installation attempt.
After setup: verify behavior before relying on it
Once a service is actually activated, check which line appears in the status area and which connection handles the action you intend to perform. Confirm usage against the service’s balance information. If something is wrong, keep the existing working connection available while you diagnose the new one. A completed on-screen checklist is a record of your review, not proof that a network activation succeeded.
A separate line is one privacy layer
Your app accounts, location permissions and cloud backups remain part of the same device unless you configure them otherwise. The no-KYC status of a service describes its identity-check requirements; it does not establish the behavior of apps or the network. The checklist below helps organise the decisions without substituting a visual status indicator for actual verification.
