T-Mobile discontinues a free number feature but a paid alternative exists [UPDATED]
T-Mobile's Proxy by DIGITS feature that gave you an additional phone number was discontinued last month.

Update from May 10, 2025:
T-Mobile tells us that the PROXY by DIGITS promo has indeed been discontinued, though this doesn't affect existing customers. The company offers DIGITS Talk and Text plans for new customers.
Yes, the PROXY by DIGITS promotion is no longer available. Our existing customers can keep their PROXY lines. We’ve also got DIGITS Talk and Text plans for new customers if they’re looking to have multiple phone numbers on one device.

The original story from May 9, 2025 follows below:
T-Mobile customer representatives apparently told a customer that Proxy by DIGITS was discontinued on April 9. Naturally, customers were not happy to hear this, but the response to the news was muted, suggesting the service was not that popular to begin with, which might be why it's not being offered anymore.
Customers who already use the service will allegedly be able to keep using it. The change only affects customers who don't already have a Proxy by DIGITS line, as they can't order a new one any longer.
Proxy by DIGITS was ideal for users who preferred using a proxy number for calls and texts. The proxy number acted like a spam folder of sorts and was useful for e-commerce transactions, social media, and other situtations where you didn't want to provide your personal number.
The best thing about it was that you got an extra number for free without a SIM card. It could be activated in the DIGITS app or online. It did have its limitations. For instance, it didn't work without the app and internet connection and did not provide data. It also did not work for shortcodes. But we are assuming that hardly mattered because the main purpose of the feature was to give you a burner number.
Signs started appearing last year that T-Mobile was considering phasing out the DIGITS service. The company started offering customers in some markets a second line with talk and text for as little as $10 with discounts and autopay.
We've reached out to T-Mobile for a comment and will update the story when we have a response.
