Android's dual-SIM settings are hidden; one fixes my constant SIM prompts

Samsung's Android phones have dual-SIM settings that are often hidden from users. This can cause problems when making calls, as the SIM picker appears before nearly every call. During a five-day experiment, a reporter had to make SIM choices about 35 times and experienced being on the wrong SIM at least seven times, resulting in unnecessary identifications.

A recent update to Google Messages improved SIM switching for texts, but switching during network issues took longer than before. Samsung introduced a per-contact SIM setting in Contacts, but it is hidden and not easily found. Google's Phone app on Pixels also has a similar option in each contact's menu. Motorola offers a more convenient feature that sets a preferred SIM after using a contact three times.

Samsung claims to support dual SIM users, but the current setup still forces users to choose between default or ask for SIM choices, leaving them with limited control over their dual SIM setup.
