I tried using a Twilio number with my bank. I found out that any service that uses SMS shortcodes for their SMS '2FA' won't work as this kind of service. SMS shortcuts are a value addon that carriers provide that is only suppose to work with real numbers.

It's possible that services more centered around VOIP vs an automation plateform might work. It's also possible that using a foreign VOIP number might work but that also might also cause issue if you try using it with a US bank.

And I'd rather not have some half baked solution using Google Voice.

If anyone knows how to get an shortcode enable number (not a short code number but rather a number that can recieve SMS from shortcodes) on Twilio or similar platform, it would be very easy to set up an SMS 2 EMAIL gateway. Perhaps if a number is ported to Twilio it will retain shortcode capabilities?

Besides finding a solution to the above problem, I suppose I could just get a GSM usb modem & SIM card for this purpose.

you can use jmp.chat, which is a SMS to XMPP service.


What's "half baked" about Google Voice for this purpose? Verification code shows up in email and hangups client, select and paste into snake oil annoyance. This has worked everywhere I have tried it (number originally ported from Sprint).

Plus the more people that give out Google numbers, the harder it will be for banks to push back on this.


I've started using a dual sim phone with a second number that I do not give out to anyone being used for companies that insist on SMS authentication.


Be sure to enable a SIM PIN on it, in the event that it's stolen/taken an attacker can't simply put the SIM in a new device to request the code.


I did not think of this. Thank you!


Hi, I’ve actually used BurnerApp to get a number that you pay monthly for. Something along the lines of 5$ for every 90 days I believe.


I tried Burner, Twilio, Textra and voip.ms. None of them played well with SMS 2FA services. Voip.ms was the best for reachability but its time to deliver for SMS messages was pretty bad.

I switched to a dual-SIM phone.
