It does use the Verizon network but not all phones on the Verizon network are "equal."   Think of it this way:  on a plane there can be first class, business class, full fare economy and budget fares.  The type of service for each class of passenger is very different even though they are all using the same plane.   Verizon similarly has multiple classes:  priority 1 is for its postpaid customers, priority 2 is for its prepaid customers, and priority 3 is for its wholesale partners such as Xfinity Mobile.   It is unrealistic to expect the same service on the Verizon network if you are a wholesale partner customer rather than a Verizon customer.  That is why Verizon service is more expensive. ...

The answer depends in part on which version you bought and how you initially activated it.  You could try backing up the phone, connecting to iTunes and selecting Update (not restore) and then set the phone up as New and try these features before restoring any personal data.  This will help if the issue is related to modifiable software on the phone itself but will not help if the issue is an incompatibility between the phone's software and the Xfinity Mobile system.    The first thing to note is that Best Buy, like other retailers, sells iPhones that are subject to the US Resellers Flex Policy.    This can, depending on how a buyer intends to use the phone, be a real limitation.  Usually, if the phone is activated on the particular carrier on which it is branded and then properly unlocked most features that are supported on a given MVNO will typically work.   However, if they do not or if the phone becomes locked to an MVNO resolving these issues can be very difficult if not impossible.   You might wish to research this matter and if you are still within the return period consider returning it if the limitations of this policy are too constraining for you.       ...

Go to Settings-General and see if there is a profile there and, if there is delete it and restart the phone.     Assuming you are in an area with a strong LTE signal (for instance you know others on Xfinity Mobile can get LTE at your location),  here are a few things to try and check after each one to see if the situation has improved:   1) turn Airplane Mode on and then off again.   2) go to Settings-General-Reset and reset network settings   3) Turn off wifi    4) Turn off the phone, remove sim, replace it and turn the phone back on again.   If none of these help, make sure there is no carrier settings update available for your phone.   If you still have problems, check the APN settings by dialing *3001#12345#* and then selecting PDP Context Info and then 0.   ...

No carrier guarantees speeds and Xfinity Mobile indicates that expected download average speeds are in the range of 5-12 Mbps.  Clearly, this implies that customers in some locations will have lower speeds than those indicated.   https://www.xfinity.com/mobile/policies/broadband-disclosures   All MVNOs have slower speeds that the Tier 1 carrier on whose network they operate and that is one of the factors that enables them to offer less expensive service.  Verizon's policies in relation to MVNOs on its network are well known.   Comparing TMobile speeds to those on a Verizon MVNO, even at the same location, is not an apples to apples comparison.   The critical issue is not the absolute level but rather whether the level is sufficient for the customer's needs and constitutes a reasonable value at the existing price point. ...

You might also wish to file a dispute under the customer agreement if you are within the specified time limit.   The primary advantage with that approach is, if you are not satisfied with the initial outcome,  the matter can ultimately be referred to an arbitrator who will independently decide the matter based on the available evidence and arbitral law.   https://www.xfinity.com/mobile/policies/customer-agreement  ...

In looking at the tech specs, I am wondering if the issue is the customized Xfinity Mobile rom.   Did you by any chance try to flash a stock or custom rom to the device? ... View more

I have managed to switch an iPhone that had always been on  CDMA to GSM by simply swapping sims.  Indeed this is exactly what Apple indicates is possible and countless iPhone users have had the same experience.   Xfinity Mobile branded iPhones are able to operate on GSM networks provided they are unlocked.  The technical capabilities of each model of iPhone sold by Xfinity Mobile are clearly described on the Apple website and are not subject to dispute.  [The situation is a little more complicated for certain GSM carrier-branded iPhones as they are not all capable of working on CDMA networks, e.g. the AT&T and TMobile iPhone 7 in native cellular mode because of the Intel modem they contain].   By the way, CDMA carriers do use sims although Verizon and Sprint use them in different ways (Sprint uses the sim just for LTE and the MEID of the device is "married" to the ICCID of the sim).   An unlocked Xfinity-branded iPhone is capable of working on a GSM carrier.  That does not necessarily mean every GSM carrier will activate such a phone as each carrier sets its own policy on what devices are permitted on its network.  What it does mean is the phone has the technical capability to work on a GSM network.   @Gravitygap wrote: This thread has tons of misinformation. First of all XFinity phones use the same network as Verizon, which is CDMA. All Europe and Canada only use GSM network ( att and t mobile in the states). If ur phone is locked u can only use w the provider that you currently have. Once you unlock your phone you can switch to a different provider, BUT it has to be under the same network. So unlocked Verizon phone will work w xfinity. Unlocked Verizon/xfjnity phone will NEVER work w GSM provider. meaning you cannot switch from att to xfinity ever. GSM network uses sim cards. cDMa does not use SIM cards. I phone always have SIM card slot (even on Verizon/xfinity specific phones). However if u unlock CDMA phone and attempt to insert SIM card, it will give u error, and will not work as your phone is not build to work w GSM. You can take CDMA phone and use oversees ( roaming). You cannot take cdma phone and switch SIM card to work oversees w a local carrier (as all European carriers are on GSM network) your phone is not build for that. The only way to switch from cdma to gsm is take your I phone apart and re-wire it, and trust me you probably can’t pull it off   ... View more

It can be said with certainty that throughput on Xfinity Mobile Personal Hotspot will not match performance on Verizon.   However, for your purposes that may not matter since the critical question for you is whether throughput on Xfinity Mobile's Personal Hotspot is adequate for your purposes and that is an empirical question the answer to which depends on the location you are in and the requirements of the trading platform and the way you use the platform's settings to optimize available bandwidth.   The odds are that unless you are in an area with a weak signal and need to run a trading platform that uses data-intensive real-time analytics, the Xfinity Mobile Personal Hotspot may be adequate most of the time.  However, for trading purposes, most of the time may not be sufficiently robust as market developments often require the ability to react in real time.   Moreover, Xfinity Mobile is intended for normal consumer use rather than mission-critical applications and therefore it probably is not an optimal solution for cases where reliability and continuous access is essential.  A more robust service, such as that provided by Tier 1 carriers is probably more suited to such uses. ...

Are you sure the phones are the same?  You can check by looking under Settings-General-About and scrolling down to Model and you will see a string that looks like this: "M......LL/A."   The Xfinity Mobile BYOD checker does state that the phone is not compatible and the Apple website provides the explanation for the incompatibility.   "Models A1778 and A1784 do not support CDMA networks, such as those used by Verizon and Sprint."   https://www.apple.com/iphone-7/specs/     ...

One thing I forgot to ask is whether you had received a replacement device under warranty.  These devices have a different code (under Settings-General-About the Model begins with "N" rather than "M") and often there are problems getting then activated on a new carrier.   There are sites on the Internet that sell GSX reports on iPhone activation policy for a fee.  There are questions about their reliability and safety and for that reason I personally would only use Apple.   You might try again with Apple and firmly but politely request an escalation to advanced support since your carrier (AT&T) assures you the phone has been unlocked.  Generally Apple tries to help customers although Apple employees will usually try to get the customer to deal with the carrier if it seems that the problem might be carrier related.  If the customer politely explains that has already been done usually that is sufficient to get Apple engaged.  The real advantage with working with Apple is that the matter can be escalated to a level where a resolution with the carrier partner can be achieved in some cases.  A poster here recently reported success in one such case.   Sorry, but that is the best I can offer. ...

OK   There are a couple of possibilities here:   1) the unlock is either not completed properly or the activation policy on the phone is not being correctly identified by Xfinity Mobile's IMEI checker.     2) the unlock has been completed successfully and the Xfinity Mobile database is not current.   Unfortunately without knowing what the actual situation is there is no easy way to identify the easiest way forward.   Here are a few suggestions to consider:   1) contact Apple Support and verify the current activation policy on the device and the date on which this policy became effective.  Have Apple Support confirm that this policy enables the phone to activate on its carrier partner Xfinity Mobile.  Make a note of the actual policy.   If Apple Support indicates the activation policy is not compatible with Xfinity Mobile, escalate the matter with AT&T and get it resolved.   2) Once you have confirmation that the activation policy is compatible, contact Xfinity Mobile again, request to speak with a supervisor, explain the situation and ask that the matter be addressed by tech support.   It might be helpful to refer to the tech specs on the Apple product page to support your case.   https://www.apple.com/iphone-8/specs/   An alternative approach would be to seek assistance from an Xfinity Mobile employee here on the forum to assist in addressing the issue.   Good luck! ...

Your concern is very understandable.  Obviously, no one can offer you an absolute guarantee you will not have any problem after a factory reset.  However, you should not and most likely will not.   I have done factory resets on several phones without any issue but not on your particular model.   If you have not set a PIN on the phone then you will not need one for the factory reset.  The PIN you used to set up the port to Xfinity Mobile is something completely different and relates to moving your phone number from your former carrier.   There is no need to remove the SD.   One thing to bear in mind is that since it has not been established for certain that the problem is a software issue, it is not certain that the factory reset will solve the problem.   As to being able to use Xfinity Mobile service after the reset, there should not be any problem.   Think about the pros and cons and wait until you are comfortable.  If you feel it useful, you might search on the web for experiences other users have had with factory resets before coming to a final decision.   Good luck! ...

A factory reset is a standard procedure whenever there appears to be a software problem on a device that does not respond to simple remedies.   It is very unlikely that a factory reset will cause any problems that cannot be fixed.   However, a factory reset will erase all personal data permanently so it is critical that such data be backed up before the reset is undertaken.   So back up your data and then follow the instructions to do the reset.   Once the reset completes, test the stability of wifi connections before you restore your personal data to be sure the problem has been corrected.   Good luck! ...

First, did you unlock your Google Voice number before submitting the port request?   If not you must do that  and the cost is $3.   Have you set a voicemail PIN?  If so, that is what you need to provide for the port PIN.  Otherwise you can use "0000". ... View more

The reality is that with any MVNO and BYOD situation, it can be very difficult to find the cause of a problem and, even if it is found, it is not always possible to fix it.  This is certainly not unique to Xfinity Mobile and is the main reason service on MVNOs is less expensive than on Tier 1 carriers.   There are some basic things a user can do to see whether the phone itself is a factor in the equation because that is often a soluable issue.   1) go to Settings-WiFi, select the network and then tap on "Forget This Network."  Then turn the phone off.  Turn the router off and back on and then turn the phone back on and reconnect to the network.   2) if that does not help, if the router is dual band, try the other band   3) back up the phone, connect to iTunes and do a restore.  After that repeat step 1.   If these steps do not fix the problem, there is a strong chance there is nothing more a user can do to resolve the issue.  There are other actions that a user can take but the chances of them being worthwhile in terms of resolving the issue are not high. ...

Are you able to view the APN settings on the phone and, if so, are they properly configured for TMobile?   If the APN settings are not visible, have you tried backing up the phone and doing a factory reset?   While the reset will erase all personal data, it should allow the correct APN settings to be populated on restart. ...
