About H2O Wireless

H2O Wireless is a prepaid, no-contract mobile service in the United States, a trade name of Locus Telecommunications, LLC of Teaneck, New Jersey, selling unlimited and pay-as-you-go plans, international calling, phones and SIM or eSIM activation on AT&T’s network through its website, dealers and retailers. Customers of prepaid carriers like this one tend to run into the same problems: refills paid for but not added, activations and number transfers that stall, data slowed after the high-speed allowance, and refunds for plans that could not be used.

Prepaid disputes are settled by transaction records. Keep the phone number on the account, the receipt for every refill and plan purchase, and screenshots of the plan and balance. For an activation or transfer problem, note the dates, the ticket number and any error message.

Refill paid but the plan not active? Start the case with us. We put the receipts and dates into a clear complaint and stay on the case, advising you what to send next.

The contact page on the H2O Wireless website, linked in the contact details at the top of this page, lists the other routes.

Refill, activation or transfer problem? Start your complaint here as well, and we push it out to H2O Wireless by email, social media and printed letters.

Who owns H2O Wireless?

H2O Wireless is owned by Locus Telecommunications, LLC: H2O and H2O Wireless are trade names that Locus uses, and Locus has its head office in Teaneck, New Jersey, with the full address in the contact details at the top of this page. Locus's federal telecom registration names Telrite Holdings LLC as its holding company, and the coverage H2O Wireless sells is AT&T's network. To escalate a complaint inside the company, write to Locus Telecommunications at that head office, quoting your H2O Wireless phone number, the ticket numbers from earlier contacts, what went wrong and when, and the outcome you want.

Send the letter by a tracked method and keep a copy with the date you sent it.

How do I transfer my number out of H2O Wireless?

To move your number from H2O Wireless to another carrier, start the transfer with the new carrier, not with H2O Wireless: it asks for the details of your H2O Wireless account, such as the account number and a transfer PIN, which you can request from H2O Wireless customer care at 1-800-643-4926. Keep the H2O Wireless line active until the transfer completes, because a number on an expired prepaid line can be lost.

Write down the date you asked for the details and any ticket number. If the transfer is rejected, ask the new carrier which detail did not match, because the account number, the PIN and the name and ZIP code on the account all have to agree.

Can I file a complaint about H2O Wireless with the Federal Communications Commission (FCC)?

Yes. The Federal Communications Commission (FCC) takes informal complaints about phone services in the US, including billing, number porting and service problems, and that covers H2O Wireless. The FCC generally expects H2O Wireless to have had the chance to put things right first, so keep a record of every call, email and ticket number.

Refill or porting problem to put in writing? Take it through our complaint process: our trained AI opens a case for you and keeps coaching on what to send and when to push.

What do people complain about most at H2O Wireless?

Nothing has been reported about H2O Wireless here yet. Our research shows what typically goes wrong at prepaid mobile carriers: refills paid for but not added to the account, activations and number transfers that stall, transfer details that are hard to get, data slowed once the high-speed allowance runs out, and refund requests for plans that could not be used.

Refill paid and not on your line, or a transfer held up? Be the first to report it: your case opens the record for the next H2O Wireless customer caught the same way.

What happens after I submit my complaint?

Your complaint gets its own public page on Complain.biz and we get to work: we bring it to the attention of H2O Wireless through emails, social media, paper complaint letters and other tools at our disposal.

And we stay with it after you file. Our trained AI opens a case file for you and keeps coaching: what to reply, when to push again, and how to escalate if nothing happens.

Can other consumers help me with my H2O Wireless complaint?

Yes. We have an active community of consumers, and complaints here are public: people who ran into the same problem with H2O Wireless can give you advice or back you up with their own story. A complaint with a community behind it is much harder to overlook.
