# SIM Card & Power

Step-by-step tutorial on inserting a SIM card and booting up the router.


# Choose Location

Good mobile signal quality is fundamental to getting a stable and fast internet connection over the mobile network. Please choose a location for the 4G router that has a good signal reception.

### Mobile Networks

There are various mobile networks, 2G, 3G, 4G, and 5G NR. Please take note of the signal bars and the symbol in the status bar of the mobile phone and compare them with the chart below.

<table><thead><tr><th width="150">Symbol</th><th width="314">Mobile Networks</th><th>Internet Speed</th></tr></thead><tbody><tr><td>5G NR</td><td>Fifth generation mobile network</td><td>Up to 10 Gbps</td></tr><tr><td>4G (LTE)</td><td>Fourth generation or Long term evolution<br>also known as LTE or WiMax</td><td>Up to 1 Gbps</td></tr><tr><td>3G</td><td>Third Generation<br>also known as UMTS / WCDMA / CDMA2000</td><td>Up to 2 Mbps</td></tr><tr><td>2G</td><td>GPRS <br>(General Packet Radio Service)</td><td>Up to 64 Kbps</td></tr><tr><td>No Symbol</td><td>If signal bars get more than 1 bar<br>you can use voice call</td><td>No</td></tr></tbody></table>

### &#x20;Signal Strength

We should input a "Fair" signal level for the 4G router. Typically speaking, 3-5 bars indicate a good signal, while 1-2 bars indicate a poor signal. No bars mean no 4G signal detected.

You can run a basic test on a mobile phone. Insert the SIM card used on the router on a mobile phone. Disable Wi-Fi on the mobile phone and go around to check its network type and signal bars. Then, choose a location with strong and stable signal reception.&#x20;

The below chart shows targeted signal quality values for 4G-LTE and 3G networks.

<figure><img src="https://2281776451-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FgV6nqomki285by8oRjoy%2Fuploads%2Fprr5DZhVQWNpqiv0Riqt%2Fimage.png?alt=media&#x26;token=2c07c988-314a-43d2-877e-06b68e131dcb" alt=""><figcaption><p> Signal Quality Chart</p></figcaption></figure>

{% hint style="info" %}
The numerical value of 2G and 3G networks is RSSI standard.&#x20;

The LTE network is RSRP standard. RSRP means Reference Signal Receive Power.

The signal values are negative numbers. A number that is closer to zero means a stronger signal. For example, -90 dB is more robust than -100 dB.
{% endhint %}


# Install Antennas

The 4G router uses 2x2 MIMO antennas on both mobile and Wi-Fi connections.

## Antenna Sockets

Please check the chart and image below about which antenna goes to which socket.

<table><thead><tr><th width="215">Antenna Sockets</th><th>Antenna Marks</th></tr></thead><tbody><tr><td>Mobile *Main</td><td>4G paddle antenna (Main Port)</td></tr><tr><td>Mobile *DIV</td><td>4G paddle antenna (Alternative Port)</td></tr><tr><td>Wi-Fi</td><td>Either Wi-Fi whip antenna</td></tr></tbody></table>

The 4G and Wi-Fi antennas have printed marks on their connectors to indicate which ports they attach to for proper configuration. Be sure to connect the antennas to their correctly labeled antenna sockets on the router, as shown in the below image.

## Install Antennas

To install the antennas, twist the antenna connectors clockwise onto the router until securely fastened. Only twist the connectors—do not excessively turn the antenna bodies, as it could damage the antenna pin or internal wiring.

All the antennas have vertical polarization. Ensure all antennas remain upright vertical once installed on the router for the best possible reception and range.

<figure><img src="/files/vtiJlNYQw9gReqNOee3w" alt=""><figcaption></figcaption></figure>

{% hint style="info" %}
The flat panels of the 4G paddle antennas have a higher performance. Please adjust the paddle direction towards the outside or signal source to receive a better signal.
{% endhint %}

{% hint style="warning" %}
To ensure optimal performance of your 4G router, position the device away from potential sources of radio frequency interference, such as microwave ovens, radio transmission equipment, and high-power electrical appliances.
{% endhint %}

##

## Upgrade Antenna

When you have a weak signal reception, please consider upgrading the 4G mobile antenna with a higher-gain antenna. The MIMO panel antenna can point towards the cell tower and receive stronger 4G signals.

To connect to the other mobile or WiFi antennas, make sure these antennas have the standard SMA-male connectors. You can use both a MIMO and a single-polarized antenna on the router. If it's a single-polarized antenna, please connect it to the mobile main socket on the left side.&#x20;


# Insert A SIM Card

The 4G router uses Nano (4FF) SIM card to connect to mobile internet networks.

## Nano SIM Card

Please use Nano-SIM cards (12.3x8.8mm) on the 4G router.&#x20;

Please use an activated Nano SIM card in the G router. If you are going to use a new SIM card, please follow the instructions from the mobile carrier to activate the SIM card.

***

## Brief Introduction

The indoor 4G router has several network interfaces, as shown in the image above. All of these interfaces work together to connect the router to local devices via Ethernet or WiFi, as well as to the internet through the cellular network.

It is important not to "Stop" or "Delete" any interfaces unless you know their functions.

### Guest (wlan0-1)

The Guest interface is isolated from the main network (192.168.20.100\~249). It uses a separate subnet, 192.168.100.100\~249, and is bound to the Guest WiFi hotspot. This interface will be activated after enabling the Guest WiFi under "Network > Wireless."

### LAN (bar-lan)

This is the interface of the leading local intranet network. It is assigned to the physical RJ45 port **eth0**. Refer to the below section to configure the local intranet networks.

{% content-ref url="/pages/aOaQqkaQUdm0Z9bg8VK4" %}
[Local Networks](/firmware/network-interfaces/local-networks)
{% endcontent-ref %}

###

### Mobile (wwan0)

The Mobile interface displays information and controls related to the 4G cellular data connection.

**Uptime:** Shows how long the mobile data connection has been active.\
**RX/TX:** Displays the real-time data usage flowing through the mobile modem.\
**IPv4:** The mobile IP address assigned by the mobile carrier for internet connectivity.

By clicking the "**Edit**" button, you can configure settings like the mobile protocol, APN, SIM card slot, PIN code, and more. Please refer to the [Mobile Modem settings](/firmware/mobile-modem) section for details.

The router should establish a mobile data connection when powered on. Using the Connect and Stop buttons, you can manually connect or disconnect the mobile broadband. Once successfully connected to a mobile network, the RX/TX counters will show live data traffic, and an IPv4 address will be assigned.

{% content-ref url="/pages/QUfndxIUjwXdrI2GRKFJ" %}
[Mobile Modem](/firmware/mobile-modem)
{% endcontent-ref %}

###

### WAN (eth0)

The WAN port is bound to the **eth1** RJ45 port, marked "PoE & WAN" on the enclosure.

DHCP client protocol It is enabled on the WAN interface and can automatically obtain the IP address after being connected to the LAN port on another internet router or modem. You can use the PPPoE protocol when linking to a landline modem and turning on the bridge mode.


# Local Networks

Configure the LAN interface to set up local intranet networks.

{% hint style="danger" %}
Do not `stop` or `delete` the **LAN (bar-lan)** interface is the DHCP server of local networks and the cornerstone of Ethernet and Wi-Fi functions.
{% endhint %}

## **Router IP Pool**

To modify the DHCP configuration, log in to the router admin and go to "Network > Interfaces," then click the "**Edit**" button on the row of the "**LAN**" interface.

### **Router IP Address**

Under the tab of "General Setup", you can modify the router IP address, netmask, gateway address, broadcast address, and custom DNS servers.

<table><thead><tr><th width="171.33333333333331">Field</th><th width="148">Default</th><th>Description</th></tr></thead><tbody><tr><td>IPv4 address</td><td>192.168.20.1</td><td>The IP address that the router uses on the LAN network.</td></tr><tr><td>IPv4 netmask</td><td>255.255.255.0</td><td>Netmask is used to define how "large" the LAN network is.</td></tr><tr><td>IPv4 broadcast</td><td>N/A</td><td>DHCP clients use broadcast to find and send requests to their respective servers.</td></tr></tbody></table>

### **DHCP Server**

Scroll down and find the section of "DHCP server" settings. Under the "General Setup" tab, you can modify the DHCP IP pool and DHCP lease period.

The DHCP server can automatically configure connected devices' TCP/IP settings and lease out an IP address from the available IP pool.&#x20;

To disable the DHCP server, you can select the checkbox of the **Ignore interface**.

<table><thead><tr><th width="117.4">Field</th><th width="102">Default</th><th>Description</th></tr></thead><tbody><tr><td>Start</td><td>100</td><td><p>The start of the DHCP IP pool.</p><p>For example, if the router’s LAN IP is 192.168.20.1 and the netmask is 255.255.255.0, a valid IP address should be in the range of [192.168.20.0…192.168.20.254]</p><p>* <em>192.168.20.255 is a particular unavailable address.</em></p></td></tr><tr><td>Limit</td><td>150</td><td><p>Define the IP addresses the DHCP server can lease out.</p><p>Continuing from the above example, if the start address is 192.168.20.100 and the server can lease out 150, available addresses will be from 192.168.20.100 to 192.168.20.249.</p></td></tr><tr><td>Lease time</td><td>12 hours</td><td><p>The duration of an IP lease. Leased-out addresses will expire after the specified period, and you must request a new DHCP lease.</p><p>If the device stays connected, its lease will be renewed after half of the specified amount of time passes.</p><p>For example, if the lease time is 12 hours, then every 6 hours, the device will send a request to the DHCP server asking to renew its lease.</p><p>The lease time can be set in hours (h) or minutes (m). The minimum time that can be specified is 2min (2m).</p></td></tr></tbody></table>

You can set up more configurations on the DHCP server under the **"Advanced Settings"** tab of the **"DHCP Server"** settings.

<table><thead><tr><th width="141.4">Field </th><th width="116">Default</th><th>Description</th></tr></thead><tbody><tr><td>Dynamic DHCP</td><td>Enable</td><td>Enables dynamic allocation of client addresses. If you disable it, you must input a static IP address on the connected devices.</td></tr><tr><td>Force</td><td>Disable</td><td><p>The DHCP force function ensures that the router will always start its DHCP server, even if another DHCP server is already running in the router’s network.</p><p>*** When connecting the router to another router via LAN cable, the outdoor router will turn to AP mode and obtain the IP address assigned from another router. You will no longer be able to access the router at 192.168.20.1.</p></td></tr><tr><td>IPv4 Netmask</td><td>NA</td><td>Overrides the LAN netmask, thus making the DHCP server think it’s serving a larger or smaller network than it is.</td></tr><tr><td>DHCP Options</td><td>NA</td><td>For example, you can assign an MTU value per DHCP with ‘26,1470’ or ‘option:mtu, 1470’. You can add more options by clicking the plus symbol (Services SMS gateway auto-reply plus symbol.PNG) next to the field.</td></tr></tbody></table>

### Physical Settings

There are three physical RJ45 ports on the EZR23T router. The "LAN" and "PoE & LAN" ports are bound to the logical port **eth0**.&#x20;

### Stop & Restart

The Mobile interface can be manually **stopped** to disable the cellular data connection.&#x20;

If the modem needs to be power cycled, it is recommended to unplug the router's DC power adapter to force a hard reset rather than using the software reboot option. Disconnecting and reconnecting power will ensure the modem undergoes a full restart sequence when plugged back in to renew the mobile broadband connection. This may help resolve connectivity or registration issues if the modem is unstable.

***

## Mobile Settings <a href="#apn-settings" id="apn-settings"></a>

To change the Mobile modem settings, go to "***Network > Interfaces***" and click the "***Edit***" button on the **Mobile** interface after logging into the router.

### SIM Card Slot

**Active SIM Card** - Select between "Primary SIM 1" or "Secondary SIM 2" from the drop-down menu to choose which slot's SIM card to use. By default, the Primary SIM 1 slot is active.

**Auto Switch SIM** - If both SIM card slots have active SIMs inserted, the "Auto Switch SIM" function can be enabled to allow automatic failover between the connections. The router handles the SIM switchover internally, so no manual intervention is required when auto-failover takes place.

Check more about [Switch SIM cards](https://how.router.works/mobile/switch-sim-card).

<div align="left"><figure><img src="/files/zr1bc3dYd0t7xcRT6VB9" alt="" width="375"><figcaption><p>General Setup Mobile Interface - SIM Slot &#x26; Protocol</p></figcaption></figure></div>

### Mobile Protocol

Mobile protocol refers to communication technology and networking standards it uses to connect to cellular networks and transport data.&#x20;

The default mobile modem protocol on the EZR23T router is "**Mobile-Data**." It has integrated the below QMI and PPP protocol and automatically invokes the most adaptable protocols depending on the mobile networks.

If your carrier does not support the default Mobile-Data or QMI protocols, follow [Mobile Protocol Guidance](https://how.router.works/mobile/protocol) to change the modem's protocol to Cellular PPP.

### APN Settings

APN, or Access Point Name, is the gateway between the mobile network and external IP networks like the public Internet. Correct APN settings are vital for the modem to connect to the carrier properly.

Typically, the router's built-in default APN values are sufficient for mobile broadband connectivity. However, some providers or data plans may utilize different APNs that must be configured manually. If unable to establish a mobile connection, contact the carrier to obtain the appropriate APN details for the data plan.

Select either the "Primary SIM1" or "Secondary SIM2" tab, depending on which SIM card's APN is being configured. By default, Primary SIM1 is the active SIM card.

Enter the APN parameters provided by your mobile carrier. Refer to the APN chart below.

Click the "**Save & Apply**" button on the bottom when finished to save settings and reboot the mobile modem. It will take a few minutes to reconnect using the new APN.

<table><thead><tr><th width="219">Option</th><th>Decription</th></tr></thead><tbody><tr><td>APN</td><td>The APN gateway address</td></tr><tr><td>PIN</td><td>PIN code of SIM card <em>*Usually non-required</em></td></tr><tr><td>Username</td><td>PAP/CHAP Username</td></tr><tr><td>Password</td><td>PAP/CHAP Password</td></tr><tr><td>Authentication type</td><td>Usually use PAP</td></tr><tr><td>IP connection type</td><td>Usually use IPv4 only</td></tr></tbody></table>
