FAQs

How can I get a sim card with a free unlimited SMS plan?

Getting a SIM card with a free unlimited SMS plan may vary depending on your location and the mobile network operators in your area. To find a SIM card with such a plan, you can follow these steps:

Research Mobile Operators: Start by researching mobile network operators in your region. Look for well-known carriers and smaller ones that might offer unique prepaid or postpaid plans.

Check Plan Options: Visit the websites of these operators and explore their prepaid or postpaid plan options. Look for plans that explicitly mention "unlimited SMS" or "free SMS."

Compare Plans: Compare the SMS-specific plans among different carriers. Pay attention to the details, such as any fair usage policies or limitations, to ensure that the plan truly meets your needs.

Visit Retail Stores: If you prefer an in-person experience, visit the retail stores or kiosks of mobile operators. Their staff can help you understand the available plans and assist you in choosing the best one.

Ask for Recommendations: Seek recommendations from friends, family, or online forums. Others who have experience with specific plans can provide valuable insights.

Online Reviews: Read online reviews and customer feedback to get an idea of the user experience and reliability of the operator and their plans.

Activate Your Plan: Once you've chosen a plan that offers free unlimited SMS, purchase the SIM card and activate the plan as per the operator's instructions.

My modem usually works for one or two hours without a problem, then I see timeout messages in the log. What causes this problem?

Ozeki SMS Gateway relies on continuous communication with your GSM modem to manage SMS/MMS messages. However, some users experience a situation where the modem becomes unresponsive after a period of operation. This can be caused by two main factors:

  • Modem Hardware Malfunction: The issue could be due to failing internal components within the modem itself, or potential bugs in its firmware.
  • USB to RS-232 Converter Issues: If you're using a converter to connect the modem to your computer, the converter might malfunction and disrupt communication.
To troubleshoot this issue, we recommend isolating the problem by connecting the modem directly to a different computer's serial port (if available). Additionally, consult your modem's documentation for troubleshooting steps or firmware updates. While not an official recommendation, some users have found success with Wavecom Supreme 10 models for maintaining stable connections. You can also explore online communities dedicated to Ozeki for troubleshooting tips and compatible modem options. If the problem persists, contacting Ozeki support directly is your best course of action. Their expertise can help identify the cause and recommend solutions based on your specific setup.

When I try to submit a message, I receive an error. What can be the reason?

Users might experience situations where SMS messages fail to send consistently through Ozeki SMS Gateway. In such cases, unreliable network coverage could be a contributing factor. To enhance message delivery success in these scenarios, the software offers a message resend functionality. This functionality can be configured by increasing the value of the "Max number of tries" field located within the "Advanced" tab of the "Server preferences" form. By utilizing this feature, Ozeki SMS Gateway will automatically attempt to resend the message if the initial transmission fails. There is a significant likelihood that the message will be delivered on the second or third attempt. However, if message submission consistently fails, a different cause might be hindering successful delivery. Here are some potential reasons to consider:

  • Insufficient Subscriber Identity Module (SIM) Card Balance: Verify that the SIM card associated with the modem possesses sufficient credit to cover message sending costs.
  • Invalid Short Message Service Centre (SMSC) Configuration: Ensure the SMSC configuration within Ozeki SMS Gateway is accurate and reflects the correct details for your specific mobile network provider.
  • Active Personal Identification Number (PIN) Code on SIM Card: If your SIM card requires a PIN for operation, it's crucial to disable it to prevent it from blocking message submission attempts.
For a more exhaustive list of potential causes for SMS submit errors, please refer to the dedicated information page: SMS submit error reasons

By systematically addressing these potential causes and employing the message resend functionality, users can significantly improve their overall SMS delivery success rate when utilizing Ozeki SMS Gateway.

Does Ozeki SMS Gateway handle a modem with multiple sim cards?

Ozeki SMS Gateway currently does not offer native support for modems equipped with multiple SIM cards. However, users seeking to leverage the functionality of multiple SIM cards can achieve this by connecting additional GSM modems to their Ozeki SMS Gateway setup.

These GSM modems can be connected to your system through two primary methods:

  • USB Ports: This widely used interface offers a convenient option for connecting additional modems. Most computers come equipped with several USB ports, allowing for the connection of multiple modems simultaneously.
  • RS-232 Ports: While less common on modern computers, RS-232 ports can still be used for modem connections. In scenarios where USB ports are limited, RS-232 provides an alternative solution.
By connecting additional GSM modems, each with its own SIM card, users can effectively expand their SMS communication capabilities within the Ozeki SMS Gateway environment.

I can send SMS, but I cannot receive with my modem. Why?

While connecting a mobile phone via a data cable might seem like a convenient option for receiving SMS messages through Ozeki SMS Gateway, it's important to consider potential limitations:

  • Conflicting SMS Software: Most standard mobile phones have built-in SMS software designed to manage incoming messages for the phone user. This software might inadvertently intercept incoming messages, preventing them from reaching Ozeki on your PC.
  • Symbian OS Incompatibility: Mobile phones based on the Symbian operating system (commonly found in older Nokia and Sony Ericsson devices) are known to have compatibility issues with Ozeki. These phones often fail to deliver incoming SMS messages and reports to the modem interface, hindering software reception.
For reliable and consistent SMS reception within Ozeki, we strongly recommend using dedicated GSM modems instead of standard mobile phones. These modems offer several advantages:
  • Optimized Functionality: Unlike mobile phones, dedicated GSM modems lack the conflicting internal SMS software, ensuring seamless message transfer to Ozeki.
  • Enhanced Reliability: Industrial GSM modems, such as Siemens TC65 or Wavecom Fastrack, are specifically designed for robust and dependable communication, making them ideal for professional applications.
If you choose a non-recommended model, ensure it supports the GSM 7.5.0 SMS standard for optimal compatibility with Ozeki. Refer to the following website for a list of recommended GSM devices for SMS messaging: Recommended GSM devices for SMS messaging

By opting for dedicated GSM modems, you can ensure reliable and efficient SMS reception within your Ozeki SMS Gateway environment.
