Google's SMS search feature went haywire in the middle of the night on Feb. 2, sending dozens of unwanted text messages to users of the service.

There are many complaints about the issue on the Google Mobile homepage and within the company's Help Forum. Of course, besides being disruptive, many of the service's users don't have an unlimited text message plan and were worried about being charged for the messages.

"Could you please try calling your carrier (e.g. AT&T, Verizon, etc.) and asking them to reset your SMS message settings," said Zeke, a Google employee that addressed the problem at 6:47 a.m on Feb 2. "If that doesn't do the trick, please respond back here and let me know what carrier you're using."

Carriers were swamped with phone calls early that morning. Since many people using several carriers were experiencing the problem, it became evident that Google was at fault.

"[My carrier] said that, since the problem is happening to customers with many different carriers, that the problem is more likely on your end than on theirs," said one of the users in a thread on Google Mobile.

The Google SMS search users started to receive text messages every seven to 13 minutes, starting at about 2:30 a.m.

Users expressed anger, annoyance and frustration.

In many of the threads, Google SMS users expressed that they would think twice before they do a simple SMS weather check with Google.

Google SMS provides mobile phone users information while on the go .

All users need to do is text message their search query to 466453 and Google texts back the results.

At about 11 that same day, another Google employee added some information to the thread of complaints.

The employee claimed that the issue was being worked on and that Google would post again when it knows that the problem is resolved for certain.

In the meantime, users were encouraged to call their wireless carrier and have Google's short codes 466453 or 46645 blocked.

About two hours later, a Google employee posted another thread saying that Google investigated this issue and found that the cause seems to be related to an error with the mobile aggregator used by many mobile providers. Google did not mention the aggregator's name.

"We've received confirmation that a fix is going out soon," Google's Zeke said. "Please let us know in the forum if you're still having problems with multiple SMS messages.

"We appreciate your assistance and patience while we looked into this issue," he said.

Users who received SMS messages that night and don't have an unlimited text message plan may be able to work out the problem with their carrier. Google is not planning on paying for these charges.

Google sent around 30 text messages to thousands of users. What this implies is this: This isn't the only problems that the Google SMS search service has faced.

On Jan. 8, the service stopped sending results back to users' queries.

Then on Jan. 15, Google confirmed issues with queries via Google SMS related to sport scores. What's next?
