internet - Getting visitors online

China Telecom used to have this great service, called 16300, that would provide non-resident visitors with a dial-up service against a local tarif. You had 16300 as a dial-up number, a login name and as the pass word. You could dial-in at any phone, where you could unplug the phone wire from the phone.
I was playing the China expert again, telling visitors about this great service, but it did not work anymore. 16300 still exists as a service, but it does not accept the old login and pass word. What is now the best possible service for non-resident visitors to get online?
