Yep, the Time Of Emergence of magic is key to saying what happens next -- and whether anything we know today would exist at all.
Interplanetary? Interstellar. A single mage with adaption and a bag of holding could easily explore out to quite a few light years on his own; a corps of mages could easily reach the nearer galaxies. Trivial, really.
Assuming, of course, nothing STOPPED them.
Note though that many people here are looking at the positives. There'd also be increases in anti-teleport technology, interference in magical scrying, etc., the Gods would get involved, there'd be more powerful attacks and defenses, etc., etc.
On my world of Zarathan, for instance, there are SOME reliable teleport links... but the baddies don't always let them work. Sometimes they interfere, and interference can range from "ended up a mile off" to "disappeared to an unintended plane" to "grabbed by the bad guy and 'ported into a secure holding cell (which gets an Antimagic Shell on it as soon as you arrive".
