Boost Mobile

Worst SIM I’ve ever seen. Even one star is too much. Overpriced and not worth it at all.

Boost runs on the full Telstra prepaid network NOT REALLY !! Boost Mobile 4 Years Experience !! I have been with Boost Mobile for over 4 years. Every year the price has increased, but the service quality has not improved. The indoor signal is very weak in Lidcombe, Parramatta, and Blacktown, which are all major areas in the heart of Sydney.… Read more

Inside shopping centres, apartments, and buildings, calls often drop and mobile data is slow or unusable.

Boost Mobile used to feel like good value, but with prices going up and poor indoor coverage, it is no longer reliable for everyday use. After being a long-term customer, this is very disappointing.

Boost Mobile needs to seriously improve indoor coverage in Sydney, especially in busy suburbs, or review its pricing for loyal customers.

I keep getting a “something went wrong” error message after trying at least five times, with no explanation at all. I tried on my mobile, tablet, and laptop, and the same error appears at the final step every time, even though everything goes smoothly beforehand with no issues on my end. I’m unable to complete the process or use the SIM card… Read more

properly. I paid $300 for this service, and this level of quality and reliability is completely unacceptable. This is a filthy and deeply disappointing service, and it feels like a complete waste of money.

I've been on Boost Mobile on and off. Here is my take: + the best network coverage in Australia + cheaper than Telstra + frequent promo for new customers + simple plans - terrible customer service. I mean you'd have to spend a lot of time trying to compaing or explain an issue, and you would only get: we're sorry, and we're appologise... not the… Read more

actual resolution. - if you want to buy a SIM card from their website - good luck, because it doesn't work!!! You will spend multiple attempts to get that online deal, but nothing will work... different browser, different email, different ID, different card, incognito mode... you'll try their online support and all they can do is say sorry, go to Telstra shop... so no online deals that they advertise

I want to share my terrible experience with Boost Mobile so that other consumers can avoid falling into the same trap. 1. Misleading advertising of the $365 prepaid plan On 29 August 2025, I purchased Boost’s $365 12-month prepaid plan. The official Boost website clearly promoted this plan as including unlimited international calls and SMS to 20… Read more

countries. That was the only reason I chose this plan.

However, after receiving and activating the SIM card, I discovered that international calls were not available. When I contacted Boost, they referred me to their Critical Information Summary (CIS), which quietly excludes international calls from this plan.

This is a classic bait-and-switch: the website advertising gives one impression, but the fine print says the opposite. Many other consumers have reported the same issue online – this is not an accident, it’s a deliberate way to mislead customers.

2. Dishonest customer service behaviour (Agent: Dinchen) When I complained, Boost’s customer service agent Dinchen admitted the problem and told me that I could port out to another provider and receive a full refund of the $365 plan.

I relied on this promise and ported my number away. But once I had done so, Boost suddenly reversed its position and refused to refund me, leaving me out of pocket. This shows a complete lack of integrity – Boost took my money, misled me about the service, and then broke its promise when I sought a resolution.

Conclusion Boost Mobile has:

Misled customers with contradictory advertising and fine print;

Provided robotic and dismissive customer service that refuses to acknowledge obvious evidence;

Gone back on its word, showing zero respect for consumers.

This company’s behaviour is, in my opinion, unlawful under Australian Consumer Law. I am pursuing this matter with the TIO, ACCC, and ACMA, and I strongly urge other consumers to avoid Boost until they clean up their misleading marketing and dishonest practices.

Rating: 0/5 – Absolutely the worst telecom experience I have ever had.

Instant regret Bought the SIM card yesterday and spent almost 48 hours with Boost staff trying to sort out my number transfer. Finally when I got my number transferred I realised their staff even cancelled my husband’s number incorrectly in process and all they said is apology now go to Telstra to sort out as we cancelled number but can’t… Read more

reinstate . So spending public holiday when all stores are closed and expected to live without number till Telstra fix the mistake done by one person who did not bother to check properly. Spent hours on phones and messages, took a long time to sort out . Unbelievable welcome to boost service for next 365 days , wish me luck.

Boost is absolutely fantastic! I must praise Boost's service attitude! I used to have a Telstra monthly plan, but after checking, I found that Boost uses the same network as Telstra but offers a cheaper price. (It saves a lot of dollars!) So I chose Boost's 365-day recharge plan. Since I wanted to keep my original number and wasn't sure if my… Read more ·  1

phone was compatible with Boost's SIM card, I went to the Boost Mobile office for help last Friday. A big thanks to Maria and John at the Boost Mobile office—they answered my questions very patiently and directly helped me with keeping my original number and activating the plan. (I'm already using Boost smoothly!) I was worried that solving the SIM card issue would take some time because my phone situation is a bit complicated, but with Maria and John's help, I got it sorted on the spot. Thank you so much, they really helped a lot! I'll be a loyal Boost customer from now on!

I had a Boost SIM delivered to my home. It was a quick delivery, after placing an online order. I put the Boost SIM in my phone during that first day, after completing the activation process online and retaining my current mobile number. When activation with the new Boost service didn't happen much later that day I rang up to ask how long this… Read more

process would take, as a few hours or up to 24 hours, is generally the norm. The service agent (SA) said it could be the same day but possibly up to 3 days. I had to put my current service SIM back in the phone at this point. Meanwhile, I thought I had put the Boost SIM in a safe place for reinserting back into my phone once the service was activated.

5 days later - still no activation.

I rang Boost up and the service agent completed the activation with my current mobile number. After putting (what I thought was) the Boost SIM back in my phone, there was still no Boost service and now my previous service was no longer available. Long story short.. the SIM in the phone was the wrong one as the correct one was now lost (but at this time I didn't know how to check this for sure).

Misplacing/losing the SIM would not have happened if the first activation process had been successful and timely.

Trying to get multiple SAs, though the online chat, to understand my issue was an absolute nightmare. At this point I had no idea whether I had the incorrect SIM card or if the activation process itself had failed. In the end I was the one having to ask the question about a possible way of knowing if I had the correct SIM in the phone. Once this was confirmed I went to the supermarket and purchased another SIM. Attempting (yes, attempting) to get the new SIM activated was just more head banging. I found out it wasn't possible to do this online by myself as of course I already have an activated (but lost) Boost SIM with my current mobile number, so computer says 'No!'. Back to Online chat.. OMG!! Chat disconnecting, asking for the same info over and over (even though I have just typed that info into the chat). The last SA requested multiple times for me to provide a contact number once he had confirmed that the online chat agents do not have the 'power' to activate a SIM. The experience of trying to make him understand that the number he wanted another SA to contact me on was currently activated with a lost Boost SIM and therefore meant that number was no longer contactable and had any service, and using my wife's work number for Boost to contact her (who knows when, but most likely at an inopportune time for both of us and when I wasn't going to be in her company) was unacceptable, was an excruciatingly painful one. I had to resort to capital letters and exclamation marks to eventually get my point across. This all happened after I had suggested I needed to ring Boost to get the new SIM activated so why persist in trying to contact me?! Finally, I was provided a number I could contact.

Bottom line. Do not remove your new provider's SIM from its packaging until you are absolutely sure the service it facilitates, has been activated and you can put it in your phone. Boost service continues to exemplify the type of service I experienced with Telstra (the last time I used their expensive crappy service was over 20 year ago) Once my SIM is activated I so much hope I do not have to use their online service again because it [Contents Removed].

I got a year plan. Trying to move the number to another provider and the boost keeps the numbers hostage... They forcing me to pay more money as the plan is not active... They do not offer any period to just receive messages and after one support transfer me to specialist team the waiting time is over an our. Telstra not helping it self with this one. Show details

Do not buy it , 100% my sim is not activated for last 10 days

Boost uses the Telstra network in Shoalwater, Western Australia. Please regard this comment as being appropriate for the area I live in: it is rubbish. Absolutely dog-poop bad. Please see the speed tests below for confirmation of my complaint. Bad most the days, worse the rest. A well known issue that Telstra evidently ignore. Show details

What an ordeal. Tried to port over number to make the most of 49 prepaid monthly deal (pay 17 per month for 3 months) but account wasn't working so called tech support and they reset my username and I purchased it through the app. Phone number never ported and couldn't get into app to activate due to some system error (see white screen below). … Read more

Issue escalated but they kept trying to call me on the number that isn't activated!

Six hours on landline later, over three days with no mobile number active then told to buy a physical SIM (posting would take 5 days to get to me) then they can activate that SIM then change it to esim. Shop only had 26$ SIMs so my expense and inconvenience again.

Fail again, escalated but no follow up call. Still unable to see billing, still can't access app. Can't use my other physical SIM work number while this damn Boost SIM is in there. So no work calls at the moment unless I use another phone!

Apparently my account has now two 26$ plans and a 49$ plan recharging at 49 not the original 17$ price. Hopeless.

Great deal if it worked but they obviously have some tech issues on their end. Will probably have to cancel and find another provider where I can access my account properly.

I accidentally placed the wrong order on Boost's website and immediately contacted their online support to cancel it. To my surprise, the agent informed me that they don’t offer an order cancellation option—meaning customers have no right to correct a mistaken order. Unbelievable! Show details

Pros - Easy website to navigate to recharge (was better with #111# option). - Fast and stable 4/5G network. - Rare network dropouts. Cons - Boost has offered competitive and value options and has always used Telstra's Network. Since Telstra acquired Boost, there have been a few price increases and fewer lower-cost plan options disappearing. … Read more

12-month plan for $150/80Gb no longer exists. It now starts from $300/290GB for a 12-month plan - far more than many light users need (including me). - Used to have $30/20GB then discontinued, replaced by $35/25GB and now its $39/25GB. - Previously had USSD feature #111# to check balance/data and recharge in favour of the app only. - Offshore Call Centre/Support (although it's common with the majority of the major Telco providers)

Overall Boost Mobile was once a competitive and value-driven telco provider, offering Telstra network access without the premium pricing of big-name carriers. However, recent changes—particularly the removal of lower-cost plans for light users—indicate a shift in business strategy. The current entry-level plan starts at $39 for 25GB, effectively pushing light data users into higher-priced plans with more data than they need. This move suggests Boost is prioritising higher revenue per user over flexibility and affordability.

Long-term existing customer of Boost Mobile and will now explore other options.

So I would give boost 0 stars if I could.I have been very happy with Telstra but I changed to boost with the esim followed everything in the app and… Read more

it said I would be connected in 4-24 hours after messaging to boost at home every night because I had no internet or being able to call or text because of boost and being lied to saying it would connect for 4 days I still have no internet couldn't do my uber eats on the weekend where I usually make $1000 still have no service from boost no phone no messaging.i will not be going back to boost useless.

Bought a prepaid sim for my wife, it wouldn't activate because it was after an expiry date and they wouldn't provide a replacement sim. $365 for no service. UPDATE: I have increased my review from 1 to 4 stars. A representative from Boost reached out to me to discuss my matter and in good will, offered to honour my purchase. Thank you Boost, I am very grateful. Show details ·  3
