As Taiwan enters a new era dominated by the “Big Three” telecom providers, monthly fees for unlimited data plans with no speed throttling have been steadily rising; Far EasTone and Taiwan Mobile have even stopped offering 4G unlimited data plans bundled with device purchases through certain sales channels. Although unlimited data plans remain the most popular choice among Taiwanese consumers, many still find the cost prohibitive and believe that signing up for these exorbitantly priced plans is simply not worth it. They are looking for plans with lower monthly fees that can still meet their general internet usage needs.
What unlimited 4G data plans with lower speeds do the three major telecom providers currently offer? Is the speed of 3 Mbps/1 Mbps after exceeding the data limit still usable? Here is a summary and explanation:
Unlimited 4G plans with no speed throttling are getting more and more expensive, which is a problem for mobile usersUsers who don’t use much data or who only use the internet for basic purposes are finding it increasingly difficult to cope. To meet the low-budget internet needs of specific user groups (such as seniors, children, light users, and backup phone numbers), telecom providers have launched “hidden” 4G light-speed unlimited data plans with monthly fees under $200. Below are videos and detailed explanations of the latest 2026 money-saving guides for the three major telecom providers’ 4G low-speed unlimited data plans:
1. Unlimited 4G Data Plans with Low Speeds from the Three Major Telecom Carriers:
What is “Unlimited 4G Low-Speed Data”?
The 4G Light-Speed Unlimited Data Plan is a plan offered by telecom providers as part of their low-cost 4G plans, which provides unlimited data at speed-capped rates of 3 Mbps and 1 Mbps after the free data allowance has been used up. These low-speed unlimited data plans are suitable for web browsing, using social media (Line/Facebook), and watching lower-resolution videos. They are typically aimed at children, seniors, and users who do not use the internet frequently.
Taiwan’s three major telecom providers currently offer 4G unlimited data plans with low monthly fees and moderate speeds. Plans that reduce speeds to 3 Mbps after exceeding the data limit include Far EasTone’s 4G 199 (3 Mbps) and Taiwan Mobile’s 4G Children’s Plan 229 (3 Mbps); Plans with a 1 Mbps speed reduction after exceeding the data limit include Chunghwa Telecom’s “Child Protection 199” (1 Mbps), Far EasTone’s “4G Senior 129” (1 Mbps) and “4G Family Baby 149” (1 Mbps), and Taiwan Mobile’s “4G Kids 129” (1 Mbps). Among these, Far EasTone’s 4G 199 plan has the lowest monthly fee for a 3 Mbps plan, while Taiwan Mobile’s “Children’s Heart” 129 plan has the lowest monthly fee for a 1 Mbps plan.
A. Far EasTone Telecommunications:
Far EasTone Telecom’s low-cost, low-speed 4G unlimited data plans: 4G 199 (3 Mbps), Far EasTone Telecom 4G Senior 129 (1 Mbps), and 4G Family & Kids 149 (1 Mbps).
Specifically, the 4G 199 plan is available only at Far EasTone’s online store. For a monthly fee of $199, it includes 1.5GB of free data per month; speeds are reduced to 3Mbps once the data limit is exceeded. The plan also includes 30 minutes of free on-network calls and 10 minutes of free off-network calls, and requires a 12-month or 24-month contract.
Among the plans with data allowances exceeding 1 Mbps, the 4G 129 Senior Plan is available only to customers aged 65 or older. It includes 1.2 GB of free monthly data and requires a 24-month contract; The “Family & Kids 149” plan has no eligibility restrictions, but the free voice minutes included with the 12-month and 24-month contracts differ!
B. Taiwan Mobile:
Taiwan Mobile’s 4G light-speed unlimited data plans include the 4G “Childlike Heart” 229 (3 Mbps) and the 4G “Childlike Heart” 129 (3 Mbps).
4G “Childlike Heart 229”: $229 per month, includes 3.5GB of data, unlimited data at 3Mbps after exceeding the data limit, free on-network calls, 20 free minutes of off-network calls, and landline calls at 1 yuan per minute; 4G “Child’s Heart” 129, monthly fee of $129, includes 1.5GB of data, unlimited data at 1Mbps after the data limit is reached, free on-network calls, and 1.8 yuan per minute for off-network and landline calls.
C. Chunghwa Telecom:
Chunghwa Telecom’s only “Light & Fast” unlimited data plan is the 4G Child Protection 199 Plan, which is available exclusively through the online store. For a monthly fee of $199, it offers 2GB of data; once that limit is exceeded, speeds are capped at 1Mbps. The plan includes 20 minutes of free on-network voice calls and a combined total of 20 minutes of free off-network and landline calls. Currently, the plan includes the “Porn Filter” service as a bonus, and new users receive a 40GB data voucher.
2. Is a speed of 3 Mbps/1 Mbps after being throttled for exceeding the data limit still usable?
To encourage users to sign up for higher-tier plans, telecom providers tend to be conservative in their assessments of the usability of speeds reduced to 3 Mbps or 1 Mbps. According to information on the providers’ official websites, a 3 Mbps connection is sufficient for watching 480p videos, browsing the web, Instagram, Facebook, and Threads, and using LINE…; 1 Mbps is only sufficient for browsing the web, making calls on LINE, and sending text messages!
In fact, with improvements in streaming compression technology, a 3 Mbps internet connection exceeds the requirements for watching 720p videos on YouTube and Netflix. Therefore, not only is it sufficient for browsing the web or listening to music, but it’s also generally adequate for watching most online streaming videos. According to the moderator’s past tests”Asia Pacific Telecom 3 Mbps Speed-Limited Internet Service“Apart from images taking a little longer to load, there’s no noticeable difference whether you’re browsing Facebook, regular websites, or YouTube.” This shows that even if your data speed is throttled to 3 Mbps, aside from slower file uploads and downloads, you don’t need to worry about general web browsing.
As for the 1 Mbps internet speed, in addition to being suitable for text chat, browsing general web pages, using Google Maps for navigation, and using LINE and Facebook,According to “,” produced by Ai Zhen seven years ago,Unlimited Low-Speed 4G (128K/256K/1M/3M/10M) The video shows that 480p videos play without any issues and meet YouTube’s recommended connection speed.
Using 4G for light browsing with an unlimited data plan (at speeds of 3 Mbps and 1 Mbps) essentially takes the browsing experience back to the early days of 3G,It’s passable for general web browsing or watching low-resolution videos, but it struggles when used primarily for streaming high-definition web series or downloading large files. However, for seniors, children, or those who don’t go online very often, the 4G low-speed unlimited data plan is still usable. If you’re on a tight budget or looking for a backup phone number, this plan is definitely worth considering!
