Questions & Answers about Jag ringer dem när jag kommer hem.

Why is the present tense used to talk about the future here?

Swedish often uses the present for near or scheduled future when a time expression or clause makes the timing clear. So present forms like ringer and kommer naturally refer to the future in this sentence. You can also say Jag ska ringa dem... to stress intention, but it isn’t required.

What’s the difference between ringer and ska ringa?

• Jag ringer dem när ... = neutral statement about what will happen at that time.
• Jag ska ringa dem när ... = adds a sense of plan/intention (“I’m going to/I will”). Both are correct; choose the one that fits your nuance.

Do I need to say ringa till dem, or is ringa dem enough?

Both are fine:

• ringa någon (transitive) is very common and perfectly correct.
• ringa till någon is also common; it can feel a bit more explicitly “to call to.” Avoid overdoing prepositions: you don’t need both an object and a preposition (don’t say “ringa till dem” and then another object).

Why is it dem and not de? And what about dom?
