Hey @tt13,
That's definitely not the experience we want you to have and we sure wouldn't want to see you go! We all rely extensively on our phones and we understand how important it is to be able to use your data while travelling!
I have a few questions to better understand the situation:
1. Are all your other services besides data working while roaming?
2. What phone model are you using?
3. Are you using a Non Fido phone? If yes, and your phone is LTE capable, have you made sure that you have right APN settings? They sould be ltemobile.apn and you can find how to check them here.
Let me know and we'll take it from there.
Hello tt13,
Had you tried to manually select the provider when you were in Dallas?

You can get an idea of cellular coverage at your destination here..
Fido/Rogers customers generally roam with AT&T or T-Mobile. There have been situations where one provider will work for voice and/or messages, but not necessarily for data. It all depends on your location(s) relative to the cellular towers as well as the bands/frequencies available at those cellular towers.
**edit** If the issue is related to the local infrastructure, there might not be much Fido/Rogers can do to improve the situation. In addition, it's possible the issue might still exist with a different Canadian provider.**
Hope this helps 
Cheers
Hello again,
I apologise, but it wasn't mentioned in your earlier posts...
To which provider was your phone connected? On what network (ie 2G, '3G', or LTE)? Is it possible there were no other suitable networks available at your location?
Cheers
Hello @Al_Daigen and welcome to the Community.
I can definitely understand that going to the US and not having access to your data couldn't be the best experience.
I can assure you that roaming works in the US for Fido and we don't have any known issue right now concerning this.
I would like to take a look at what was discussed so far on your account concerning this.
I'm sending you a PM now, talk to you soon.
That definitely doesn't sound right!
The fact that you need to reset the Network Settings each time might indicate an issue with the device. That being said, we have a few things to check before to make sure that it is not an network/ SIM card issue. You mentioned that it was working before you changed your plan, we'll check this out too!
I'll send you a PM and we will continue over there
Hello Ranata,
Welcome to the community!
Sorry to hear that you're still having these issues. Just to clarify, though, was your previous plan also with Fido or from a different provider? If it was a different provider, was it Rogers? If it wasn't Fido or Rogers, it's possible the cellular towers from the other provider are better suited for your location. You can get an idea of your surrounding cellular towers here.
If you are located in an area better covered by the other providers, your phone should be able to connect to their networks using extended coverage (Fido-EXT). However, you should note that its usage is meant to be on a temporary basis only. If you do not spend most of your usage on the Fido/Rogers networks, the service may be blocked.
Also, you initially noted you're missing important calls as well. That might suggest a general reception issue as they are not transmitted via a data connection.
I understand you have a LG G3 phone. Was it purchased from Fido? If purchased from elsewhere, have you verified it has sufficient compatible bands/frequencies? You can verify those bands/frequencies here.
In addition, what network mode setting is your phone currently using? Is it GSM/UMTS(WCDMA)/LTE? Have you tried to disable LTE (ie setting GSM/UMTS(WCDMA)) to see if that helps?
Have you verified whether there are any roaming blocks on your account?
**edit** Also to verify, since the phone is LTE-capable, it should be using ltemobile.apn. You can verify those settings here.
As well, are you able to test your SIM in a different phone or test another SIM in your phone?**
Hope this helps
Cheers
Hello again,
Thank you for the additional information!
I'm glad to hear the LTE APN seems to help with cell data. Are you still having to reset the network settings on your phone, though? Have you considered testing your SIM in a different phone or testing a different SIM in your phone? Repeatedly changing SIMs could possibly damage the SIMs. If your SIM is damaged, replacing it might help.
I understand you have been using Roam Mobility recently for your trips to the US. If you wish to use Fido Roam, you might consider testing your Fido SIM on your next trip. You could bring your Roam Mobility SIM for reassurance. If I remember correctly, you do not have to purchase usage in advance. If Fido Roam does not work, your could purchase Roam Mobility via Wifi at your destination.
As previously mentioned, you might have to manually switch networks while in the US. Fido/Rogers coverage outside of Canada relies on the local infrastructure at the destination. The coverage of some providers might not be as extensive as others. In addition, it's possible a location might not get any coverage. You can get an idea of cellular coverage at your destination here.
The moderators should be able to provide information regarding any possible roaming blocks via PM as that would require access to your account details.
Hope this helps
Cheers
Hey @ranata, we can send you the PM
Just one final question though. Have you tried connecting to a different American network to see if that changes anything?
As you're not on our network, the problem may lie with the American network. I suggest testing a different one.
Let us know and we'll go from there!
