    Network service is horrible.

    I switched to Xfinity 2 years ago, worst decision I've made. The mobile data doesn't work everywhere, especially at my home. I have to strongly rely on wifi to search the web. The customer service is horrible too. Save yourself the hassle and go somewhere else.


    In the city of Boston the service is terrible, customer service is even worse. Transferred back to VZW wasn’t worth the savings l.

    Worst mobile service to use traveling to AFRICA

    If there was 0 star, I would give it to Xfinity Mobile. I was charged $1,015.69, I travelled to Kenya and tried to use my phone internet but it wasn't working at all. It kept saying no internet. I called a representative and they help me turn on the data roaming but X finity mobile internet was still not working. I gave up and bought a simcard line in Kenya called safari com and used it for my stay there. When I travelled back to the US, I realized that for the month of May they had charged me $1,015.69 dollars for internet use. Internet that was not working. After I called and let them no I was having a problem with the internet connection. I have called them more than 7 times spoken to representative they kept saying that they have put in a case. I have been on a phone call which then for hours and yet nothing has happened. The last time I called they said they are listening to the phone recordings and would call me in 1 hour. I have been waiting for that call for a month. The worst mobile service ever. I regret leaving T-mobile. If you ever want to travel to Africa and want to use your mobile service PLEASE PLEASE don"t use Xfinity Mobile. You will regret, I mean how is it possible to spend over $1000 in a month on internet that was not working.

    The worst mobile service.

    The worst mobile service. I wish i found this site before entering a contract with them. Phone never works. I keep calling them from hubbys phone, i have to turn on my data to send messages that are attachments. Cant make calls or send sms. Changed sim cards ,3 times. Restart phone constantly. They blame the phone that they gave me amd want me to deal with lg.

    Bad Customer Service

    We switched from Verizon to Xfinity Mobile and were told about all these promotions we would get. We could also bring over some of our phones and tablets.

    After the account was set up, I was ready to start moving phones and tablets over. Guess what tablets were not supported with bringing your own device. The sales rep told me wrong.

    We had a difficult time porting the phones. I spent hours on the phone with Verizon and Xfinity mobile IT, and finally, after a month, we got things moving.

    But the one free phone and gift card we were promised never happened. I was told by customer service that I need to call every couple of months to get my reimbursement for the free phone and keep waiting on the gift card. So the next time I called, they said no, that's not what happened your promotions dropped off because you didn't activate the phones in the correct amount of time. I then said what about the $200 gift cards? Those dropped off, too, but we will escalate, and you will have an answer in 5 business days.

    Here we are five business days later, and they need to escalate and let me know if our promotions will be reinstated. I will say the service is the same as Verizon, but good luck if you have any issues at all! I'm ready to go back to Verizon if they deny my promotions.

    Disastrous Switch from Verizon to Xfinity

    If you are thinking about switching from Verizon to Xfinity stop immediately. I was a 20-year+ Verizon customer. The hold times for Verizon customer service got quite long, but they always were helpful and resolved the issue. Thought I would try something different and save a little bit of money each month. I should have stopped after we figured out that the representative at the Xfinity store lied to us about the benefits of switching. They gave us a credit for the mistake which was extremely painful to access each month. The answer from customer service with Xfinity is allows “no”. They are difficult to get a hold of and it is difficult for them to understand your problem. With Xfinity mobile you are literally on you own. Switching to Xfinity Mobile was a terrible decision and I cannot wait to get back to Verizon.

    Horrible customer service.

    I switched over to Xfinity mobile when I lived inside city limits. As soon as I moved away from the city they would not offer cable or phone service. They went ahead and used my old address as a platform for my service and charged me triple because they didn't service my area. After that i have been attempting to switch my service over to at&t. My phone is paid off and Xfinity locked me out of all other companies. Do not get mobile service through Xfinity. Horrible company!

    Poor reception everywhere, low tier signal

    Low tier reliability and signal. Do not recommend

    Great price. But that's it...

    I have been an Xfinity internet customer for over 5 years. There's no other real choice in my area. They've improved over the years and all in all I'm happy.

    Then I decided to go to Xfinity mobile. What a bad decision that was. I got the Samsung Galaxy A13. I've had it for 35 days now.

    On day 2 I started noticing dropped calls and very poor connection. I called xfinity. Didn't get anywhere. Was aggravated and just dealt with it. I don't use the phone a lot so I thought whatever...

    Then it got worse. On the 9th day I tried calling 6 times. Each time calls kept dropping and/or bad connection and they couldn't hear me. Couldn't get anywhere and gave up. I just continued to deal with it. And then I finally had to try using the phone while out away from home. It said I had no phone service. Which also meant I had no GPS. I got completely lost and had a very difficult time.

    It's absolutely scary since I'm disabled and rely on portable oxygen tanks. If I break down or take too long getting home, I can run out. Especially if I can't call for help. I was still within the 30 days. I called 4 more times and STILL can't get anywhere. Calls constantly drop and service is poor.

    Called 8 more times 2 days after the 30 days was up. Couldn't keep a signal and gave up again. Then tried a few more times today. Only 5 days past the 30 day window.

    I've been trying to get help since the beginning. I'm wanting away from this phone and service. Now they're saying I must pay off the (non-working) phone and can't return it because it's past 30 days.

    Do yourself a favor...STAY AWAY from them.

    I gave 2 stars because they have a great monthly rate. That's all they have though.
