Then you're wasting your time looking for a phone app. Invest in multiple types of high quality locks, use them properly, and hope for the best- realistically, that's all any of us could do.

TMobile Pay As You Go will let you put a sim into any unlocked phone. The plan doesn't even have a rate for data service. I've used it on a first generation iphone for over 4 years. However, this app would only work if it doesn't require any data service.

But back to the previous question, yes we pay to receive texts and phone calls unlike other countries; it is arguable more fair this way, have the cost of the call split between the 2 service providers. Or is cell phone service simply free in your country?

Not going to happen for me. I would need a chip planted in the bike that would give me the location of the bike via phone or computer. Kinda of like the chip for dogs.

I don't think there is such an implanted chip for dogs. something they wear on their collar yes - but not implanted.

I believe there does exist a Lo Jack like device for bicycles that is generally(??) put in some place that thieves wouldn't check and won't take off.

And, as Robble points out, (as far as I know) they only implant RFID chips in dogs, GPS trackers are put on the collar.

I had a kryptonite new york on the previous bike. Believe me, there's no mechanic lock they don't break in less than 5 minutes.
Here's an interview of a thief (it's in Italian but you can use google translate): https://life.wired.it/news/mobilita/2...iciclette.html
I bought again a kryptonite but my only hope now is Bike anti-theft because now I know i can't relay on the lock.

I suggest a folding bike and take it inside with you..

IDK is there a RFI chip on the bike, like LOJACK?

a bike stripper makes that a moot piece..
