What is HLR lookup?

HLR (Home Location Register) is a centralized database where one can find a detailed info about each subscriber of a mobile network. HLR lookup is used to check the status of mobile numbers and to filter out numbers that are no longer in use. You can use our HLR lookup service directly from your Control Panel.

Is it possible to change the sender ID?

We offer a full-featured bulk SMS service, which includes the support of a dynamic sender ID. Any alphanumeric string can be used to present your application or brand where supported by carriers.
Sender ID: “From” field parameter encoding.
– NUMERIC ORIGINATOR: The source address and the destination address in international format must start with the country code, without any leading “+” or “00”. The length of an international originator is limited to 15 digits.
– ALPHANUMERIC ORIGINATOR: The max. length of an alphanumeric originator is 11 characters.
The following characters are supported: ‘abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789’.
If any other character is used, the SMS delivery might be affected (“originator altered” or “delivery failed”).

Why are my text messages only 70 characters long?

SMS body length is limited to 140 bytes, which makes up 160 GSM-encoded characters (7 bits per character) or 70 Unicode-encoded characters (2 bytes per character). If your message length is limited to just 70 characters, it means that you are requesting Unicode encoding.

Can I send long text messages?

Yes, you can. A long text message is split into segments of 132 bytes each (152 GSM characters or 66 Unicode characters). Due to the nature of mobile communication systems and networks, different segments of one text message may arrive in any order. The mobile device uses SMS segmentation information to reconstruct the message correctly.
Please note that it’s not always the case that 160 characters fit into a single text message. Some characters (“extended”) from the GSM alphabet such as the £ sign require 2 characters – they need an ‘escape’ character + a character. Such ‘escape’ characters are also considered when deciding where to divide the message into segments.

What are the regulations regarding bulk SMS marketing?

Bulk SMS marketing regulations vary from country to country. For example, there are very strict laws regarding bulk SMS messaging in the USA. In most countries, it is legal to send bulk SMS only provided you have your customer’s consent to use their mobile number for SMS marketing purposes. You are strongly recommended to check the laws of your country or consult a lawyer to make sure you stay clear of the legal trouble when you send bulk text messages.

Why did my text message fail to deliver?

Carrier Spam Filters

Most carriers protect their subscribers from what they label as objectionable content or spam. They filter out unwanted messages using spam filtering technology. However, such filters are far from being perfect and sometimes they classify legitimate text messages as spam. Spam filtering technologies vary from carrier to carrier and get improved all the time, which makes keeping track of what is being filtered out a complicated thing to do.


We cannot ensure SMS delivery to roaming numbers due to Carrier Interconnection Agreements. Basically, this is related to Routing Carrier not having Interconnection Agreements with the roaming Networks.

More Hops, More Points of Failure

With each extra hop to reach the final user, the risk of failure goes up. Sometimes text messages have to cross as many as 5-6 SMS gateways before they get delivered. Some out-of-date telecom protocols that connect these SMS gateways can create congestion, which might cause the text messages to get lost.

Sending the Wrong Content

Not all languages are supported on all handsets. For example, if you send a text message in Chinese to a French mobile phone, it will be delivered, but it won’t be displayed to the phone user. Binary messages won’t be displayed to an iPhone user either. Also, some carriers filter a number of keywords (for instance, the carrier’s own name) to protect mobile users from fraud.

Handset Cannot Receive SMS

Major reasons that prevent mobile devices from receiving text messages are the following:

  • the phone is out of reach
  • a full memory
  • roaming
  • temporary disconnection

Portability Failure

Sometimes mobile numbers get transferred from one network to another. There are numbers that look like the original network, but, in fact, they refer to a different network operator. To make sure the text message is routed correctly, carriers use network lookups. However, they are costly, and not all providers can afford them. Some carriers don’t support such lookups at all. Also, some portability databases get updated only once per 24 hours.

Why do I need to pay for non-delivered text messages?

You pay for all text messages that have been sent regardless of their delivery status because we still have to pay the carrier for their transmission.

What causes text message delays?

Location Issues

The location of the sender or receiver can be the cause of delays in text message delivery.  A delay may occur if either of them is:

  • on the border of two cell coverage zones
  • outside a network’s coverage area
  • in a spot where the network signal is blocked (e.g. in the mountains)
  • in an old building with poor cell phone reception.

Mobile Device Issues

The most common problems with a mobile handset that may cause delays in SMS delivery:

  • a device that has been turned off
  • a weak or uncharged battery
  • if a device has an adjustable antenna that has been damaged / has not been fully raised
  • a full memory
  • temporary disconnection

Different Networks

When a text sender and receiver are using different mobile networks, it can lead to texting delays.

Network Traffic

SMS delivery speed is affected by texting during periods of massive network use. Heightened mobile traffic can cause congestion on the local network, which, in turn, might lead to setbacks in the delivery of text messages to the mobile device.

What happens when a message is sent to a Temporarily Absent number?

In most cases such messages will be placed in the Carrier’s Retry Scheme.
They will be delivered when the number becomes available. If it doesn’t happen within 1-72 hours (the duration is set by the user), these messages will expire.
