Re: Origin online login is currently unavailable

@bunnyboo007  Please use this method to uninstall and reinstall Origin if you haven't already:

If that doesn't help, please set your phone as a mobile hotspot and connect to that.  Make sure the phone is using data, not your home wifi.  Even if you wouldn't want to download your new packs using your phone's data plan, you'll at least get to purchase them, and it's a useful test.

You should also be able to purchase packs through the EA website:
