The Smart Terminal mobile data plan is designed to ensure you can always process payments, even if your Wi-Fi is down or unavailable. However, like any resource, your **data plan has limits**. This article explains how your data plan works, why it's important to be mindful of your usage, and most importantly, how to take steps to prevent service interruptions. ## What is the mobile data plan designed for? --- A mobile data plan can be [added to your Smart Terminal](/v1/docs/mobile-data-plan-for-smart-terminals) to provide a crucial backup and mobile connectivity for your business. Think of the data plan like **a reserve gas tank.** - **It is designed for one primary purpose:** Processing payments—securely sending the transaction details when your Smart Terminal is not connected to a Wi-Fi network. It is **NOT** designed to be: - **Your main internet connection:** Your terminal should connect to Wi-Fi whenever possible when in use. - **A source for heavy downloads:** Downloading large files will use up your data allowance very quickly. | ![](https://cdn.document360.io/4e721329-1a9d-4ef0-8d2f-497e0c1f185a/Images/Documentation/sparkle.png) | We are a payment technology company, not a mobile data provider. We provide this data to enhance your service, but it's important to keep usage within the intended limits. | | --- | --- | ## Why data limits matter --- While your Mobile Data Plan provides instant access to the internet, being mindful of your usage prevents service interruptions. --- ### Risk of Interruption Data service may be **paused or turned off** for terminals that consistently use far more data than the plan limit. If this happens, your terminal can't process payments until you connect it to **Wi-Fi** or contact support to re-activate your data plan. | ![](https://cdn.document360.io/4e721329-1a9d-4ef0-8d2f-497e0c1f185a/Images/Documentation/settings.png) | Your plan is intended to cover **up to 100 MB per month** for standard business operations. | | --- | --- | ## 3 key ways to reduce high data usage --- The vast majority of data usage on the Smart Terminal comes from **data coming *into* the terminal** (downloads), not from payments going out. Think of it as pulling a large file from the internet. Here are the top three actions you can take to significantly reduce your data consumption and ensure uninterrupted service: --- ### Tip 1: Prioritize Wi-Fi for back-office tasks Always connect to **Wi-Fi** before you make any changes that involve pulling data from your Helcim account, such as: | **High-usage activity** | **Why it uses data** | **Recommended action** | | --- | --- | --- | | **Product management** (adding, moving, or changing products) | The terminal has to **download** new or updated product lists, descriptions, and pictures. | Make all product changes in your Helcim account through the browser on your computer or tablet. Then, ensure your Smart Terminal is connected to **Wi-Fi** before you pull the latest changes. | | **High-resolution logos** on digital receipts | Your terminal has to **download** the logo image file for every transaction when disconnected from Wi-Fi. | Head to the [section below](/v1/docs/smart-terminal-data-conservation-guide#tip-2-optimize-your-receipt-logo) on the optimal logo size. | ### --- ### Tip 2: Optimize your receipt logo If you have a very large or detailed [logo](/v1/docs/design-receipts#logo) configured for your digital receipts, it will be downloaded frequently, which uses a lot of data. **Resize your receipt logo** to be a smaller file size (e.g. under 50KB). Your logo doesn't need to be high-definition for a receipt! If you are unsure how to resize it, [refer to our FAQ section](/v1/docs/smart-terminal-data-conservation-guide#faqs). ![An example of a digital receipt generated for a Helcim merchant.](https://cdn.document360.io/4e721329-1a9d-4ef0-8d2f-497e0c1f185a/Images/Documentation/receipt-example-new.png) A branded receipt with a custom logo --- ### Tip 3: Use mobile data only as a backup If your business has a physical location, **we strongly recommend connecting your Smart Terminal to Wi-Fi as your default connection.** - **Why?** Wi-Fi is faster, more secure, and is a limitless source of data that won't risk service interruption for your Smart Terminal. - **A note on updates:** You do not need to worry about app updates using your mobile data. The Smart Terminal is set up to ensure that major software updates will **only** occur when connected to a **Wi-Fi** network. --- ## Wi-Fi troubleshooting tips for your Smart Terminal --- If you're having trouble connecting to your Wi-Fi, here are a few simple steps to try: 1. **Forget and reconnect:** - Tap **More** from the bottom menu. - Go to **Hardware Settings > Network.** - Tap on the **gear icon** next to your Wi-Fi network and select **Forget.** - Find the network again and reconnect, double-checking your password. 2. **Restart the Terminal:** Simply turning your Smart Terminal off and on again can often fix temporary connection problems. 3. **Check Signal Strength:** Make sure the terminal is not too far from your Wi-Fi router. A weak signal will slow down transactions.

We recommend using it as a **backup** or when you are truly mobile. **Do app updates consume my mobile data?** No. To save your data and ensure stable operations, major software updates will **only** download when your Smart Terminal is connected to a **Wi-Fi** network. **What happens if I use more than the recommended 100 MB?** Your terminal may be temporarily disconnected from the mobile data service. You will need to connect to **Wi-Fi** to process payments until you contact Helcim Support to review usage and reactivate mobile data. **Where can I go to check my exact data usage?** If you are concerned about your usage, please [contact our Support Team](/v1/docs/how-to-contact-support), and they can provide details and specific recommendations based on your recent activity. **Is the Helcim Mobile Data Plan included with my Smart Terminal?** The Mobile Data Plan is currently free to enable. However, beginning on March 1, 2026, it will cost a monthly fee of $7.00/month in the US and $9.00/month in Canada. This is a **monthly charge**, not a per-MB charge, and is applied for any month the SIM card is activated. **How do I make my logo smaller for my receipts?** You don't need expensive software like Photoshop to make your image file smaller. Both Mac and Windows computers have free, built-in tools that can do this quickly. | ![](https://cdn.document360.io/4e721329-1a9d-4ef0-8d2f-497e0c1f185a/Images/Documentation/pencil-white.png) | **Remember:** The goal is to reduce the image file size to under 50KB so it downloads faster and uses less data. | | --- | --- | **If you are using a Mac (using Preview)** 1. **Open the Image:** Double-click your logo file. It should open automatically in the **Preview** app. 2. **Adjust Size:** Go to the menu bar at the top and click **Tools** → **Adjust Size** 3. **Reduce Dimensions:** In the pop-up window, make sure the unit is set to **pixels**. You can significantly reduce the numbers for the width and height (e.g. if it's 3000px wide, try reducing it to 500px). 4. **Save the New File:** Click **OK**. Then, go to **File** → **Save As** and save the resized logo with a new name (like "Logo-Small") so you don't lose your original file. **If you are using Windows (using Paint or Photos)** 1. **Open the Image:** Right-click on your logo file and select **Open with** → **Paint** (or **Photos** on newer Windows versions). 2. **Find the Resize Tool:** - **In Paint:** Click the **Resize** button (usually at the top). - **In Photos:** Click the **three dots** → **Resize**. 3. **Reduce Size:** Choose to resize by **Pixels** or **Percentage** (try 50% to start). Enter smaller numbers for the width or height. The program should automatically adjust the other number to keep your logo from looking stretched. 4. **Save the New File:** Click **OK** or **Save a copy**. Save the resized logo with a new name to keep your original logo safe. After resizing your logo, you can reupload it in the Receipt Theme Designer with [these steps](/v1/docs/design-receipts#logo).
