Question
Preserve calls and texts when you want to test mobile internet rather than social isolation
If the question is constant internet access, keep the parts of the phone that are not the question.
When it fits
- A 'phone detox' removes every communication channel at once, making the result hard to interpret.
When to avoid it
- Modern messaging often depends on data rather than SMS; define exceptions from actual communication needs.
A question to ask
Is the problem direct communication or constant internet access? · Which phone functions must remain available for safety and relationships? · Can the online functions move to a deliberate device or place?
Why it matters
The 2025 RCT isolated mobile internet while leaving texts and phone calls available. Borrow that logic when the research question is online access: keep essential direct communication and remove the always-available feed/browser layer. This makes the intervention less disruptive and the mechanism easier to interpret.
An example
Keep family calls and two-factor SMS while removing browser/social-media mobile data during the trial.
Check your result
The trial targets the suspected mechanism without unnecessarily cutting essential human contact.
Keep this limit in mind
- Modern messaging often depends on data rather than SMS; define exceptions from actual communication needs.
Evidence and sources
The mobile-internet RCT preserved phone calls and text messages while blocking internet access, allowing a more specific test of mobile connectivity.
