I have my Taiwan phone number linked to a few banks, brokerages, and other sites that require SMS 2-factor authentication. This becomes a minor problem when I am abroad for vacation or work and cannot receive SMS on my +886 number.
I am worried about being locked out of important services like my bank if I cannot receive the SMS code to login. The other issue is that most taiwan services like banks only allow local numbers and you cannot use an international virtual number like Google Voice.
Any easy way to receive SMS messages while abroad but also have a +886 number? Are there specific carriers that have international SMS plans?
I always receive text msgs on CHT # whenever I am abroad (same with wife who has different telecom company), and there are no charges.
The charges are if someone calls your Taiwan cell phone when you are overseas and you answer. You are paying the transmission fee from Taiwan to wherever you are. Do not answer, unless you want a heart attack on your next monthly bill.
I know it’s not particularly helpful, but it’s the same issue the other way round: I have several German mobile numbers at multiple carriers, and none of them work for SMS receiving in Taiwan. That includes a “real” monthly paid SIM card, a prepaid card, a virtual SIM and a real SIM of a sister company of that virtual SIM provider. If I remember correctly at least one worked for a while, but since a few years only voice works. No SMS whatsoever (OK not counting the SMS “Welcome to Taiwan! Reply XYZ to enjoy mobile internet service for an enormous amount of money per tiny amount of data!”). Customer support was useless, didn’t get anything to work.
Next time I’m back home I’ll change my setup there: probably set up an android phone with remote access, so that I can receive SMS in Germany to the German SIM card and read them by remote access to the phone.
My uk bank uses my Taiwan number, i couldn’t input it on the app but after verification they did it over the phone, they also have an app i can use to log in.
As for Taiwan bank the SMS’s are ok when travailing (but i have a post pay plan), you can normally log in with a card reader connected to your computer and your bank card, this may be a back up option.
Google Voice gives you a virtual US number that can receive SMS messages. I’ve also found many services that block Skype numbers for 2FA will accept a Google Voice number. Google FI gives you an actual SIM you can use in your phone. I use both extensively.
