4G LTE FAQs and Support
What is SingTel doing to enhance the 3G network for customers?
SingTel is continuously investing to expand and enhance our network to ensure high quality and reliable mobile services. In the last 3 years, we have invested more than S$2 billion across all our networks, including mobile. Here are some examples of what we are working on right now:
- All 4G customers have been upgraded to 150Mbps. Customers can enjoy the maximum speed of 150Mbps with a supported handset.
- We are upgrading our 3G network to offer download speeds of up to 42Mbps. This is double the 21Mbps speed of existing 3G networks. All 3G customers will be upgraded to 42Mbps by August 2013. However, a supported handset is required to enjoy the 42Mbps upgrade.
- We are implementing 3 and 4-cell carrier technologies to double the traffic handling capacity at all 3G sites. You can refer here for the coverage updates. This will be completed by early 2013.
- Our 4G nationwide network, with speeds of up to 150Mbps, is the first in Singapore to offer dual-band street coverage for 95% of the island.
Why am I getting weak coverage in MRT tunnels? What is SingTel doing to improve coverage?
The capacity of $mobile base stations in MRT tunnels and stations is shared among many users, and this may result in a slower broadband experience during peak periods.
SingTel is working with SMRT and the other mobile operators to enhance the coverage in MRT tunnels and stations. The mobile infrastructure in tunnels and stations is shared amongst the operators. To avoid disruption to train services, work for the upgrades in the MRT is performed during hours when trains are not in operation and tunnels are accessible to our engineers. The progress of the upgrade work is dependent on the maintenance windows allocated to us by SMRT. We try to work as quickly as possible within the limited time.
Why do I experience poor reception at home and in the office? What is SingTel doing to improve coverage in these locations?
There are various factors that may affect coverage, and these are often due to the inherent nature of mobile technologies. For example, users may sometimes experience weak reception in locations where signals are blocked by walls and structures.
These issues are not unique to the SingTel network and could affect customers of any operator. Sometimes reception issues may be due to the configuration of the customer’s mobile device or its ability to receive signals.
In HDB blocks, condos and office buildings, operators provide coverage at public access areas such as lobbies and common corridors. We require permission from building owners and the authorities to install our mobile equipment. The schedule of deployment and equipment location sites are often not within our control and sometimes, our requests to install new infrastructure are rejected. However, our engineers do their best to expedite the process as much as possible.
Users may also experience weaker reception if their office or apartment is not located near to shared mobile infrastructure and signals are blocked by walls and structures. That is why many customers choose to connect their mobile devices to their WiFi-enabled fixed broadband networks when at home or in the office.
SingTel has an ongoing programme in place to enhance the network. Some of the upgrades that we are currently working on are summarised in the answer of Q1.
Why do I experience slow speeds in shopping malls? What is SingTel doing to fix this?
The mobile infrastructure in most shopping malls is shared among the mobile operators. During peak periods, the capacity is shared among many users, thus resulting in slower download speeds.
SingTel is continuously investing in its mobile network to enhance capacity and coverage. Please reference here for the upgrade schedule for major shopping malls across the island.
Is SingTel's 3G network deteriorating because of your 4G network?
No. Our 4G network expansion does not affect the quality of our 3G network services in any way. Our 3G and 4G services operate on separate networks. As more mobile users adopt 4G services, we expect the quality of our 3G services to improve.
What is 4G?
It's commonly known as fourth generation mobile network and technically termed as Long Term Evolution (LTE) with speeds faster than 3G.
What is the 4G technology which SingTel is using?
SingTel is currently running 4G on LTE 1800/2600. All 4G/LTE operators overseas might be running on different technology therefore resulting in network compatibility issues when customers bring in 4G smartphones from overseas.
Why does my 4G smartphone & 4G dongle from overseas not work on SingTel's 4G Network?
Due to different 4G technology adopted by different operators around the world, your 4G smartphone might be configured to run only on a specific country's 4G network and thus not compatible with SingTel's 4G LTE network.

How can I be assured that I will enjoy typical speed range of 3.4Mbps – 12Mbps when I sign up for the 4G plan?
It's a typical range of download speeds that you can experience 80% of the time, over a 24-hour period at various locations with 4G(LTE) coverage. If a user moves out of 4G to 3G coverage, he will experience a typical download speed range of 1.7Mbps to 4.8Mbps, 80% of the time. The speed range may vary between users and is subject to device used, hardware and software limitation, 4G network coverage/traffic, distance between user and base station, nature of built-up area, source of website and other external factors.

If you are currently holding to a 2G SIM card, you will need to change out to 3G SIM card. For existing 3G SIM card users, you will not be required to change out your SIM cards.
Customers on 3G USIM will need to change to 3G Micro SIM if the 4G smartphone is only Micro SIM compatible. SIM card charges will apply.
I own a 4G smartphone and have subscribed to 4G service. Will I be able to enjoy a higher 3G speed when I move out of 4G to 3G coverage?
Yes, you will be able to enjoy 3G connectivity with download speeds of up to a theoretical limit of 42Mbps. (The speed range may vary between users and is subject to device used, hardware and software limitation, 4G network coverage/traffic, distance between user and base station, nature of built-up area, source of website and other external factors.)
Will I be able to enjoy a higher 3G speed even when I turn off my 4G/LTE settings on my device?
Yes, you will be able to enjoy 3G connectivity with download speeds of up to a theoretical limit speed of 42Mbps. SingTel's 4G service provides mobile Internet access that is up to five times faster than existing 3G-based smartphone services, with one-fifth of the network latency, hence you are strongly encouraged to turn on your 4G / LTE settings on your device in order to experience the 4G speed.
I noticed that all my voice calls are made on 3G instead of 4G. Why is this so?
4G network is a mobile data network therefore voice calls are still currently supported on 3G instead. When a voice call is made or received, 3G/2G signal will be reflected. After the call is completed, 4G smartphone will switch back to 4G based on the availability of 4G network coverage.
I noticed that the call connection is slower and LTE is switched to 3G when the call got connected. Why is it so?
4G network is a mobile data network therefore voice calls are still currently supported on 3G network instead. When a voice call is made or received on 3G, the 4G Smartphone will display the 3G network. After the voice call is completed, 4G smartphone will switch back to 4G based on the availability of 4G network coverage within 10-12 seconds, depending on various 4G phone models.
I noticed that I could not receive calls occasionally but instead I have receive SMS alerts about the missed calls. Why is it so?
When you are out of mobile coverage whether in 2G, 3G or LTE network, you will not be able to make or receive calls. When an incoming call arrives, the network will have the caller ID recorded and sent to you via SMS – when you go back into coverage.
