US Cellular email to text: still working, but plan your alarm switch

US Cellular email to text, at number@email.uscc.net, was still reported working in 2026, and no shutdown date has been announced. But T-Mobile bought US Cellular's wireless business on August 1, 2025, and T-Mobile's own gateway reportedly stopped in 2024. Keep remote site alarms texting through whatever happens next by changing one address on a day you choose.

  • US Cellular

Published:

Canal pump PLC emails 5551234567@email.uscc.net; the US Cellular gateway replies 250 OK but drops it, so no text arrives. The same alert sent to canal-pumps@welco.ai goes through Welco to the phone. The email reaches Welco and the phone shows: “Welco: [Canal Pump 3] Pump FAIL, no flow at 4:22 AM. Reply STOP to opt out.”

Animation: the old carrier address 5551234567@email.uscc.net is replaced with the Welco address canal-pumps@welco.ai, and alerts arrive again.
  • Still delivering in 2026, per EmailToTxt's July 2026 check and SigSpan. No end date has been announced.
  • T-Mobile closed its purchase of US Cellular's wireless business on August 1, 2025, per the T-Mobile newsroom.
  • T-Mobile's own tmomail.net gateway reportedly stopped with no notice.
  • You can switch now, on a quiet day you choose.

What a calm switch gets your remote crew

  • Pump alarms that don't hang on a gateway

    A canal pump or well alarm reaches the crew phone as a text, whatever T-Mobile decides about uscc.net.

  • Your schedule, not the carrier's

    Move in a slow week, before irrigation or harvest. Nobody has to scramble after a missed alarm.

  • Night alarms reach the person on call

    Send after-hours alarms to the crew member on call that night, and daytime ones to the shop.

  • Carrier changes stop mattering

    If a crew member keeps their number and moves carrier, nothing changes in Welco.

Is US Cellular email to text still working?

Yes, as far as anyone has reported. SigSpan and EmailToTxt both list it as delivering in 2026. Texts go to number@email.uscc.net, and picture messages to number@mms.uscc.net.

We are not saying it has stopped. This page exists because its future is less certain than it was a year ago. See the full carrier email-to-text timeline for the others.

Why the T-Mobile purchase matters for your alarms

One company now runs both brands. Here is what that company has done with gateways so far.

  1. T-Mobile's own gateway goes quiet

    tmomail.net reportedly stopped without a public date. Read the details on our T-Mobile tmomail.net page.

  2. T-Mobile buys US Cellular's wireless business

    T-Mobile closed its purchase of US Cellular's wireless business on August 1, 2025.

  3. uscc.net is still reported delivering

    No end date has been announced. Nobody outside T-Mobile knows what will happen to uscc.net.

  4. Switch on a day you pick

    If uscc.net does change, you may get no warning. That's the case for moving while things still work.

Should I move my US Cellular alarms now?

  1. 1.Does any alarm, pump panel or logger email an address ending in @email.uscc.net or @mms.uscc.net?
  2. 2.Would a missed alarm from that site cost you water, stock or a crop before someone drove out?
  3. 3.Has it been more than a month since anyone tested that alarm path end to end?

Answer the 3 questions to see your result.

Remote sites that lean on a crew member's phone

Sites far from town often email one person's phone when something trips. These are the alarms we'd move first.

Switch on your own schedule in 15 minutes

With the gateway still working, there's no rush on the day itself. Pick a quiet week, outside your busiest season. A carrier switch checklist helps you find every address.

  1. List each US Cellular address

    Note every system that emails uscc.net, and which crew member's phone each address belongs to.

  2. Open Welco and confirm the crew phones

    Sign up using a work email address and have your business checked. Invite each crew member to join with their own phone and reply YES to the confirmation text.

  3. Approve the sending system

    Add the email address your panel or logger sends from to your approved senders. Welco refuses mail from anything else.

  4. Dry-run with test mode

    Turn on test mode and trigger an alarm. You'll see the text Welco would send, without sending it or using credits.

  5. Go live and remove the old address

    Turn test mode off, put your Welco address in the system and delete the uscc.net one. Send one live test to a crew phone.

Move before the gateway decides for you

Set it up while the old path still works, then switch it off.

A canal pump alarm, from telemetry email to text

Telemetry loggers send readings with long headers. Welco keeps the pump, the problem and the time.

Alert email from telemetry@district.example.org, subject “CELX 204417 Alarm”. Welco trims it to one text of 91 characters: “Welco: [Canal Pump 3] Discharge pressure LOW, 12.4 PSI at 5:10 AM. Reply STOP to opt out.”

Text received: Welco: [Canal Pump 3] Discharge pressure LOW, 12.4 PSI at 5:10 AM. Reply STOP to opt out.

Animation: the alert email "CELX 204417 Alarm" is trimmed into one text: "Welco: [Canal Pump 3] Discharge pressure LOW, 12.4 PSI at 5:10 AM. Reply STOP to opt out."

A water district moved its SCADA alarms off carrier gateways the same way.

Frequently asked questions

Is US Cellular email to text shut down?

Not as of the latest reports. SigSpan and EmailToTxt both list email.uscc.net as still delivering in 2026, and no end date has been announced. What changed is the owner: T-Mobile bought the wireless business on August 1, 2025.

Why does T-Mobile owning US Cellular matter for my alarms?

T-Mobile's own gateway reportedly stopped around December 2024 without a public notice. Now that it runs US Cellular too, the same could happen to uscc.net. Nobody has said it will. But alarms are the wrong place to find out by surprise.

Should I wait for US Cellular to announce a date first?

We wouldn't. A date may never come, as T-Mobile's own gateway showed. Switching now costs a short setup on a day you pick. Waiting means switching in a hurry, maybe after an alarm went unseen.

What is the US Cellular email to text address format?

It is the 10-digit mobile number followed by @email.uscc.net, for example 5551234567@email.uscc.net. Picture messages used @mms.uscc.net. To find them in your systems, search contacts and notification lists for uscc.net. Other formats are in the gateway list for every carrier.

Will crew members need a new phone or plan?

No. They keep their phone, plan and number. Welco sends them a confirmation text once, they reply YES, and alarms arrive as normal texts that start with Welco:. They can reply STOP at any time.

What does a small district pay to replace the US Cellular gateway?

Welco runs on monthly message credits, not seats, so there is no fee per crew member and no hardware or setup fee. Trimming each alarm to one short text keeps the credits per alarm low. A 7-day free trial with 15 credits lets you test one pump site before you choose a plan.

Switch your US Cellular alarms while they still work

Set up Welco on a quiet day and retire the gateway. Check plans or start free.
