3G Network in Bangladesh: Dead or Just Slower? 2026 Status
Updated: November 2026. 3G in Bangladesh is being phased out, not just slowing down. Banglalink closed its 3G network in May 2024, Robi is reported to have retired its 3G the same year, and active 3G subscriptions fell by about half in the first seven months of 2026. Grameenphone still appears to run 3G, but we found no confirmed final switch-off date. If you rely on 3G, the sensible plan is to move to a 4G SIM and a 4G phone.
Operator by operator
| Operator | 3G status (as reported) |
|---|---|
| Banglalink | Reported as the first operator to shut 3G nationwide, in May 2024, to move resources to 4G |
| Robi | Reported as having shut 3G in 2024; network now 4G and 2G |
| Grameenphone | Still offers 3G according to a September 2026 BSS report; no confirmed final date found |
Banglalink
The Daily Star and TBS reported that Banglalink became the first Bangladeshi operator to phase out 3G, closing its network on 5 May 2024 so it could concentrate on 4G. Note that a September 2026 BSS report still lists Banglalink among operators with 3G services. That conflicts with the 2024 reports, so if you are a Banglalink user, confirm with the operator. See the Banglalink network guide.
Robi
Robi had said it would phase out 3G, starting in a few districts. The BSS report of 9 September 2026 says Robi shut its 3G service in 2024 and that around 70 percent of its customers are on 4G, with the rest on 2G. See Robi news and updates.
Grameenphone
The same BSS report says Grameenphone still offers 3G. Earlier reports said it planned to close 3G and asked users to get a 4G SIM, and some sources say operators must give customers and the regulator 90 days notice before ending 3G. We could not find a confirmed final date, so check the app or care line. See the Grameenphone network guide.
How fast the decline is
BSS reported that active 3G subscriptions fell by 1.07 million, or 50.47 percent, from 2.12 million in January 2026 to 1.05 million in July 2026. Over the same period 4G subscriptions rose from 113.49 million to 121.92 million. In other words, 3G is already a small slice of the market and shrinking quickly.
Is 3G dead or just slower?
Both descriptions miss part of it. 3G was never fast by today's standard: its real-world speeds were far below 4G, and a crowded 3G cell could be slow. The bigger issue is that operators move spectrum from 3G to 4G, which improves 4G but leaves 3G with less capacity. So where 3G still exists it can be slow, and where it has been closed it is simply gone. The old fallback is 2G for calls, and that is also due to end under BTRC's proposed roadmap. Read about it in our 2G shutdown guide.
What 3G-only phone users should do
- Check the phone. If the specs list 2G and 3G only, mobile data will fail as 3G closes. A 4G phone is needed.
- Check VoLTE. Calls move to VoLTE on 4G networks, so make sure the new phone supports it on your operator.
- Replace the SIM if asked. Even with a 4G phone, an old SIM may not use 4G. Visit an official care centre or an authorised retailer with your NID.
- Check 4G where you live. Our 4G guide explains coverage, and 5G status is covered separately.
Cheapest way to upgrade
You do not need an expensive phone. Check entry-level 4G models from brands such as itel, realme or Tecno, and the 5,001-10,000 taka range. Always confirm 4G bands and VoLTE, ask whether the phone has an official warranty, and be careful with unregistered phones, since handset registration is becoming stricter.
Why operators close 3G first
Operators pay to run every network layer: sites, power and spectrum. As more customers move to 4G, a lightly used 3G layer becomes costly. Closing it lets the operator reuse spectrum for 4G, which gives faster data to more people. Many countries have planned 2G and 3G switch-offs, so Bangladesh is following a global pattern. Shared towers, covered in our edotco guide, are re-equipped for 4G and 5G as older layers retire.
A quick checklist before you buy a new phone or SIM
- Look for LTE or 4G in the spec sheet, and confirm the bands used by your operator.
- Look for VoLTE support, since calls on 4G-only networks depend on it.
- Ask the shop for the IMEI and make sure the phone is registered, so it does not get blocked later.
- Check whether the phone is official or unofficial: official units carry a local warranty, while unofficial ones are often cheaper but may not be covered.
- Ask your operator whether your current SIM needs swapping, and whether any data balance or number carries over.
Doing these checks once avoids paying twice. A cheap phone that lacks VoLTE can end up useless for calls even when 4G data works.
Frequently Asked Questions

Not completely. Banglalink and Robi are reported to have closed 3G in 2024, while Grameenphone still offers it, according to BSS in September 2026.
Will my 3G phone still work for calls?
It may fall back to 2G for calls while 2G lasts, but data will stop where 3G is closed.
Do I need a new SIM for 4G?
Often yes for older SIMs. Check with your operator.
When will Grameenphone close 3G?
We did not find a confirmed final date. Check with Grameenphone directly.
