I am sorry for your loss. You may want to maintain the account on the lowest plan until you are sure there are no accounts with your husband's phone number attached for 2FA are left unaccessed and/or closed. You could also suspend the account via lost/stolen (before renewal at midnight eastern) if you want to maintain voicemail access or by removing autopay and reactivate before day 89/90 for 30 days service and suspend again so you keep access to the phone number if necessary.
I still run across the odd account after 5 years that my late partner had that I have needed to close or access that I needed to reset the password to do so and maintaining the phone number has made it hassle free. You may also want to consider passing the account along to another family member or friend who could use a rewards earning account that lowers their monthly bill possibly to $0? Or you may have someone who had a special connection with your husband like a grandchild or neighbour who might find comfort in having the account as a bequest?
Alternatively you could donate the account.....I actively seek $$ rewards accounts to pass on to members of society with low or fixed incomes who would really appreciate being able to stay connected with a mobile account that they can afford to budget for with their limited funds. If this is something you would consider please feel free to contact me via private message.
I'm also twice widowed so if you just need a sympathetic ear or someone to talk to I am happy to provide support in that regard as it takes time but it does get a little bit better every day.
