My BlackBerry Email Cannot Transmit

Print this articleYour BlackBerry’s inability to transmit email can be caused by an assortment of reasons, some that you can fix and others that you cannot. Your device relies on an Internet connection to a Post Office Protocol, Internet Message Access Protocol or Simple Mail Transfer Protocol server for sending and receiving email.

If your phone is unable to transmit email, it may have lost its network connection. Most BlackBerry devices’ network settings default to the connected position, but sometimes these settings can inadvertently become disabled. Checking your phone’s settings, which are accessible from the device’s home screen, will give you the ability to reactivate or enable network connectivity. Most BlackBerrys connect to the 2G or 3G wireless networks, or both, and are compatible with Wi-Fi settings. You can use each of these connections to send and receive email, but will experience problems if the BlackBerry’s connection is not established.

Network Problems

High network traffic volume, power outages and stormy weather can cause a mobile phone, such as a BlackBerry, to fail to send and receive cellular transmissions, including email. In these conditions, cell towers, which act as cellular transmission relay stations, will either retain the transmission until the condition has been resolved or will attempt to divert the transmission to a nearby tower. If the tower holds on to the transmission, it will appear as if your email has been sent, but the message will not arrive at its destination until the tower has sent the transmission. If the tower attempts to divert the transmission, you may experience a failure to transmit prompt. In these situations, all that you can do is wait for the condition to be resolved on its own.

Wi-Fi Issues

Connecting to the Internet through your BlackBerry’s Wi-Fi feature requires a wireless router that has a wired connection to a phone or cable line. Most routers have a limit in relation to how many devices it can provide Internet access to, which are typically five. Each Wi-Fi router’s Internet connection has access to a limited amount of bandwidth. As this bandwidth’s capacity is neared or reached, transmissions can become sluggish, which could cause your BlackBerry to fail to transmit email. Occasionally, the Internet service provider’s overall network traffic can also affect subscribers’ Internet performance, which could become slow or non-existent for a period of time. Disconnecting some of the router’s connected devices may help you successfully transmit email through this mode.

Considerations

POP, SMTP and IMAP servers can become overwhelmed with network traffic or may experience technical difficulties; if that happens, they will fail to work or will crash. When this happens, your BlackBerry will be unable to transmit email messages. If your email issues persist, sending messages via the device’s messaging feature, which supports text and multimedia messages, can help circumvent the situation until the email problems have been resolved.
