1pMobile Reviews 

Consider cautiously if you would like to purchase the Pay-as-you-go SIM because you are a low-volume user of data.
They require a 10 pounds minimum spending over a 120 days period.
I have just found out after finishing the purchase; their advertisement did not mention a single word of this limit. (although technically it was disclosed in the T&C)

What a greedy bunch this lot are, just recently topped up with £10.00 credit and about two weeks later they take nearly all your credit for charges, and they done the same to my wife.

Site couldn't accept payment using new account.
Decided to leave and join another mobile company.

Absolutely disgusting service from 1p Mobile. The connection drops constantly and I spent an entire week trying to get reliable internet from them with no success. Customer experience has been frustrating from start to finish. Save yourself the stress and just go directly with the big networks like EE, Vodafone, or O2 instead.

An absolute joke. Ordered my sim in time for when my old plan finishes but my sim still hasn’t arrived and so now I’m being charged daily by my old network, as I can’t leave until I use the PAC code - I also only have a certain amount of time to use it! EVERY time I’ve called (way over 10) to chase up my sim, the lines are busy or I’m cut off. Recieved one email response but now waiting for them to get back to me again. Can’t reach anyone! Terrible customer service and I’m just going to go somewhere else because this is so irritating and poor.

Excellent options and service so far.
Ordering was easy. Once the SIM arrived set up was seamless.
This SIM is for a very low but regular Data service. The value, top up duration and management of the SIM/account is great.
Recomended

Very good price. Reliable connection. Easy to use site

Since buying this SIM
I've not been able to use my data plan

I moved our family mobiles from EE to 1pmobile and ported our existing numbers as well. I found the process with 1pmobile so easy to manage. The website is logically laid out and it is simple to navigate. In addition the communication throughout the porting process was excellent and timely.
The service appears identical to EE (1p use the EE network) coverage and voice quality has been excellent and we live in a rural area.. We use wifi calling at home and have no issues at all.
Lastly, the 1p mobile plans suit our usage style and are great value compared to EE.

Everything is fine when it works but the network goes down regularly and there is no way to contact customer service - the number (when you finally track it down) either rings out forever or gives a message saying they're busy and to try again later. Unfortunately this is a pretty big deal for a communications company and a complete failure at the most basic level of what they are supposedly set up to provide so they need to exit stage left and let a real company step in instead (I will obviously be moving to someone else)

Zero issues. Put the SIM in, ported my old number and signal is noticeably better than O2.

Best coverage since I have lived in East Yorkshire, left o2 and after 2 years of hardly ever having signal and finally have mobile data nearly 100% of the time in this area!

Early days as only just joined, but so far all is rosie. Easy activation of sims and easy management on the website. Signal coverage good too in the areas I’ve been. Time will tell

Very quick and easy to change networks and keep existing number. Being a normally low user the pay rate is good for me.

Easy to set up, back up dongle and router recognised the new 1p Mob sims. Clear and easy website for top up etc.

How am I supposed to top up and get a new bundle when the website is down most of the time? Today I am getting a 500 code error! If I email (which I have done previously) I have to wait days on end for any help.

So efficient! I have just transferred from my previous
mobile network supplier to the 1pMobile plan of 50GB for £10 every 30 days. The transfer was absolutely seamless. I was sent a number of detailed and helpful emails during the process, and the porting of my old number went completely smoothly. My online account has all the details I need, and the Customer Service, by phone, was quick, helpful and efficient too.

Unlimited is not unlimited. I use a lot of data, and today my sim stopped working for data. Thought this was a little odd. It seems like there is. 500gb cap that is well hidden in their terms and conditions. The use of "Unlimited" in this context does violate ASA rules. This has been annoying as they have then used all available credit in my account for any data over that.

Customer service is also nonexistent.

No warning, not notification when it went over the limit. Not happy at all. Will look for another provider for all the sims I have over 3 accounts.
