Public Mobile only offers roaming service in the US. However there are options for your pm service. Read the spoiler below. Luckily local sim cards and plans in the UK starting at £5/1-3gb+texts/calls.
You can turn off autopay and allow the account to suspend at the of your current 30 day cycle but this is your least advantageous option. Pay and reactivate by day 85 or so.
If you have an account balance that exceeds your plan amount then you need to suspend via the lost/stolen feature in your account before midnight eastern on the evening of your renewal. Then on day 85 or so resume your service to pay and reactivate.
Suspending via lost/stolen before midnight eastern will keep your voicemail active allowing you retrieve voicemail and any verification sent by phone calls. However your rewards will not be applied to your account. Moderator/CSA contact after paying and reactivating is necessary to have the rewards** applied manually. **Points program may or may not be affected by this glitch....yet to be confirmed.
Voicemail can be accessed by calling your pm number from a different phone by calling your phone # and pressing * once connected and entering your 4 digit voicemail pin #.
If you don't have an account balance or enough balance to cover your plan amount you can suspend via lost/stolen after midnight but before 2 am eastern on the day of your renewal. Once your rewards have been applied (usually by 12:15 am et) then suspend your account. Voicemail access will be lost.
Switching to the $15 plan with rewards helping to cover a partial or full amount of your plan allows you to call forward your pm number to your voip (like fongo or textnow) number before you leave Canada.. Now any incoming calling to your pm number will ring thru to your voip number while on wifi or mobile data (w/a local or global sim card) You can access your voip # voicemail for all voicemail messages.
Most important mark on your calendar day 85 of your suspension and day 90. Do not forget when you must unsuspend your account via lost/stolen and/or pay and reactivate your service so you don't lose your phone number and account. Happy travels and Stay--Safe!
@MANTAS If you are going with local prepaid, Lebara is a good one. 3 is good too and it offers better coverage in other European countries
Also, if you think you will need access to your bank and email and they are currently setup with 2FA with SMS, make sure you change it before your trip, maybe email or Authenticator App
Unfortunately not, but it would probably be more reliable and cost effective to get a local prepaid option where you are going or use a voip app for your texting/calls.
