How to see who he is texting?

If "he" is an adult partner and you do not have his consent, no product — ours included — will legally show you who he is texting, and the ones that claim to are how people end up charged instead of answered.

The routes that actually work. Ask, or agree on open-device access; a partner who refuses all transparency has already told you something. If you hold the family plan, the carrier portal gives message and call metadata — number, date, length — which often settles "is something going on" without any content. In a divorce or custody matter your lawyer can subpoena the message records, and that evidence is admissible where anything pulled covertly is not. A licensed investigator working under your jurisdiction's rules is the fourth option. Do not install anything on his phone: unauthorised access to stored communications breaks the Wiretap Act and ECPA in the US (18 U.S.C. 2510-2523), the Computer Misuse Act 1990 in the UK and stalking laws elsewhere, whoever pays the bill.

If "he" is your minor son, the picture changes. A parent may monitor a child's Android phone they administer, with the child aware of it — that is the case Ultimate Phone Spy is built for: SMS/MMS and call logs in one dashboard (SMS tracker), plus geofencing and web history (parental control features), from $16/month annually. Android 4.0+, Windows and Mac; no iPhone support, no remote install, no iMessage.

Be honest about what you need. If you fear for your safety, or you are documenting a partner's behaviour, the usable records are the ones on your own account and in your lawyer's hands, not a spy app. A domestic-abuse advocate or family lawyer costs nothing at first contact in most places and keeps you on the right side of the line. The account-level versus device-level mechanics are in this thread.
